How To Write Ionic Equations?

It is quite fascinating that most of the day to day products we use whether it is in cooking, cleaning or anything household item for that matter is a result of some chemical reaction. Take the common table salt; it is nothing but NaCl (Sodium Chloride) with some iodine added to it in some chemical process (so as to rule out diseases such as goitre). When two or more compounds react, they form other compounds or substances. For example, when an acid and base react, a salt is the result along with water in most cases. Take for example, the aqueous solutions of hydrochloric acid and sodium hydroxide reacting with one another. This reaction gives the following product – sodium chloride and water. Let us take this example up and study it in the form of an equation.

HCl (aq) + NaCl (aq) -> NaCl (aq) + H20 (l)

Aq stands for aqueous solutions and ‘l’ stands for liquid. The above is the complete formula or complete molecular equation. To understand what happens when these compounds interact, we must further break this equation down into ions that participate in the reaction. This is also quite an important topic when it comes to assignments and this is one area where most students seek chemistry assignment help.

Transforming a complete molecular equation into a complete ionic equation

Before we get to this, we need to understand the different types of compounds there are:

  • Ionic compounds
  • Molecular compounds

Ionic compounds are formed between metals and non-metals or between metals and ions that are poly atomic. An ion in turn is the result of an atom having lost or gained electrons in its quest to attain a stable valence electron configuration and the resultant +ve or –ve charge the atom carries. Examples of ionic compounds are sodium chloride, magnesium nitrate and so on. Whenever an ionic compound dissolves in a solution that is aqueous, it will ionize and the ions will retain a charge.

Molecular compounds on the other hand are formed only between non metals. Carbon dioxide, water and glucose are classic examples of molecular compounds and they exist only as complete molecules. They don’t ionize and thus don’t carry a charge.

Here are a couple of things to remember before you get down to writing net ionic equations:

  • Ionic compounds always ionize when dissolved in water and retain their charge on ions.
  • Molecular compounds never ionize and exist only as molecules.
  • Ionic substances may also be insoluble and in such cases they are written in the full formula and never as ions. This is simply because to ionize, they need to be soluble!
  • Weak bases and acids are always written in the molecular form.
  • It is important to learn which substances are soluble and which are not and this can be done using the solubility chart. Make sure that you at least go through it once!

The following molecular equation can be written as:

HCl (aq) + NaCl (aq) -> NaCl (aq) + H20 (l)

Complete Ionic Equation:

H+ (aq) + Cl¯ (aq) + Na+ (aq) + OH¯ (aq) —> Na + (aq) + Cl¯(aq) + H2O(ℓ)

Spectator Ion and what it does

A spectator ion simply does what the name suggests; it is a mere spectator and does not react. It is present in the same form in both the reactant and product side. In the above equation, two ions are spectators – sodium and chloride. Understanding this is important and most students turn towards an online chemistry tutor to understand all about spectator ions and writing net ionic equations. The main reason as to why students struggle with identifying the spectator ion is because:

  • They don’t know to write the proper complete molecular equation
  • They don’t understand the ionization concept and thus don’t know how to break the equation into the ionic form
  • Solubility of substances is one area that most students are unaware of and hence the problem with identifying substances that will ionize and those that won’t.

Writing the net ionic equation

For our equation, take away the spectator ions, the resultant participating ones are the following and this gives us the net ionic equation.

H+ (aq) + OH¯ (aq) —> H2O (ℓ)

Remove all the spectator ions and only the ones that participate will appear in the net ionic equation.

Where are net ionic equations used?

Net ionic equations are used in the following areas:

  • Redox reactions or reduction oxidation reactions
  • Double Replacement reactions or Double displacement reactions
  • Acid Base neutralization reactions


Net ionic equations are quite an important and help students understand what happens when various compounds react. Getting this fundamental idea right will help them work with complex reactions such as double displacement and redox reactions. Thus, getting the best chemistry homework help there is to work on this area is important to achieve mastery in this topic and ace exams.

What Is A Polar Covalent Bond?

Chemistry is replete with topics that are tricky and hard to understand at the first go. Chemical bonding is one such topic that students find a bit hard to make sense of as the concept of electron clouds in atoms interacting with one other and sharing or transferring electrons is difficult to understand. There are primarily to different kinds of bonding – ionic and covalent and the polar covalent bond. Read on to learn as to what a polar covalent bond along with some examples.

What is a polar covalent bond?

Simply put, a polar covalent bond is formed when atoms (or their electron clouds to be more specific) interact with one another and electrons are shared between them in the process. While in an ionic bond, the electrons get transferred, here a sharing of electrons takes place and this happens in electron pairs. When a single pair is shared, the resultant bond is called the single covalent bond, when two pairs are shared; the resultant bond is called a double bond and so on. There are again two distinct types of the covalent bond – polar and non-polar. The polar covalent bond is typically formed as a result of unequal sharing of electrons between the participating atoms.

Learning such an important concept is no longer possible with classrooms alone today as the student ratio is very disproportionate and students seldom get individual attention. An online chemistry tutor is thus the best hope for a student to understand this tricky concept and learn all the requisite details about it well. Keep reading to learn about some examples of a polar covalent bond.

Some popular examples to understand the polar covalent bond

The compound called Hydrogen Fluoride is an easy example to understand this intriguing concept. Most students require help in this area and are often flummoxed when it comes to understanding this type of bond and seek chemistry homework help from online platforms to get the detailed explanation and step by step explanation of how the bond is formed between Hydrogen and Fluorine.

Structure of Hydrogen Atom: Hydrogen is the first element on the periodic table and has an atomic number 1. Thus, the number of electrons in its valence electron shell (outer shell) is one.


Structure of Fluorine Atom: Fluorine is the ninth element in the periodic table and has an atomic number 9 and has seven electrons in its outermost shell.


Thus, hydrogen requires one electron for stability while fluorine requires also requires one electron for stability (To complete its octet) and these two elements share an electron to form a polar covalent bond. Since polar covalent bonds are all about unequal sharing, Fluorine pulls the electron towards its octet resulting in a partial negative charge while hydrogen has a partial positive charge.

Most of the organic compounds form polar covalent bonds and thus understanding this concept completely is of utmost importance in organic chemistry. This is perhaps why most assignments are allocated in this area at school and students seek chemistry assignment help online to score better and understand the concepts involved clearly.

Understanding The Alkene Hydrohalogenation Mechanism Taking Place In Organic Chemistry Reactions

Alkenes hydrohalogenation involves forming a carbon double bond by breaking a single bond, which is again followed by halogen having hydrogen added through an electrophilic addition. Then the substituted carbon will have a halide added with the help of Markovnikov’s rule. The result obtained is a haloalkane product known as alkyl halide.

Alkene Hydrohalogenation Mechanism Taking Place

Brief summary of Hydrohalogenation Mechanism

Nucleophilic pi bond targets for the electrophilic H bond in the H-X reaction, which results in breaking of the pi bond. Through Markovnikov’s rule, H adds up to the less substituted atom of carbon. This causes a deficit of +1 charge in the more substituted atom of carbon. This provides room for negative halide to form a bond by attacking carbcocation. Finally, what is left is a haloalkane called alkyl halide. Keep in mind that an inert solvent is a must to carry out the entire reaction.

Electrophilic Addition

Detailed explanation of Hydrohalogenation Mechanism


MECHANISM FOR REACTION OF ALKENES WITH HBrThe H-X molecules observed around such as H-Cl, H-Br, and H-I are absolutely high polar. This means that you can expect the electrons between hydrogen and halogen getting hogged because of the tendency of halogen that is highly electronegative. Hence, halogen becomes partially negative, making hydrogen partially positive. Because the pi bond is present at extreme ends of carbon skeleton, they are conveniently distracted by other neighboring molecules. And since, electrons get attracted towards the positive charge, they will possibly look out and reach the electrophile passing by that is positive or even partially positive.

Markovnikov's rule

As soon as an H-X bond passes by alkene, pi bonds get attracted towards hydrogen atom that is partially positive. To trade for the hydrogen atom, out of two any pi electron has to let go off the carbon atom already present in the bond. Now by applying Markovnikov’s rule, carbocation takes place with the more substituted carbon atom. Now since the less substituted carbon atoms haven’t released the electrons, they are singly bound to hydrogen. However, hydrogen can form only a single carbon bond. Hence, halogen acquires the electrons from less substituted carbon atom, and gets floated away in a solution full of negative charge as well as complete octet.


Remember, negative halogens are known as nucleophiles and they get attracted towards electrophiles that are positive. Hence the alone halogen loses electron pairs to attract carbocation forming a sigma bond. Because carbocation took place with more substituted carbon, halogen winds itself with that carbon atom.

alkyl bromide

Solvents play a big role in dissolving reagents as well as reactants without actually hindering the actual process. For this particular reaction we use non polar protic inert solvents such as CCl4, CHCl2, and more. When halide breaks away from hydrogen, the role of halide comes into play. A cage like thing is formed all over negative halogen when the solvent makes use of its partially positively charged hydrogen atoms. Hence, carbocation is prevented by letting off halogen. In fact, what happens is a one of the solvent molecules uses electrons in order to confront carbocation.
