Net ionic equation is formed by removing spectator ions from both side of ionic equation.

Helo reders welcome to “” today we will discuss about net ionic equation, basic concept of ionic and molecular equation and FAQ.

Lets get started,

What is Net Ionic Equation?

Net ionic equation is one type of chemical equation in which only elements, compound, and spectator ion that are present in complete chemical reaction. in case of net ionic equation, spectator ions compound are present in both side of ionic equation. it mean that, spectator ion are involved in both side of chemical reaction. Such as,

  1. Reactant side &
  2. Products side

Net ionic equation by removing the spectator ions because spectator ions are present in both side of the ionic equation.

When spectator ions are cancel from the both side of the ionic equation. then net ionic equation is formed. net ionic equation is,

Ba(2+) + SO4(-) – BaSO4


You know that, net ionic equation is balanced with the help of equal mass and equal charge of each elements in the chemical equation.

it mean that, if you want to balanced the chemical equation then it is necessary to required equal number and equal charge of each elements on both side in chemical ionic equation. It mean that, It should be equal mass and equal charge for the balance of the chemical equation.

Explain the Molecular equation?

Molecular equation is one type of equation in which the formulas of compounds are written as though all substance exist as molecules.

you know that, molecular equation show what is happening in this reaction and also show what will be reactant and products. this is a better way to determine about basic concepts of this reaction or resultant of this reaction.

For example;

When the aqeuos solution of Bacl2 and k2so4 are mixed, solid Baso4 and aqeuos 2kcl is formed. using this information, you can write a balanced molecular equation for the reaction.

Bacl2 (aq) + k2so4(aq) – Baso4 (s) + 2kCl (aq)

this is molecular equation

Write the state of each substance (s, l, gas, aqueous) and identify which of the ionic compound are soluble in water. and also identify which of the ionic compound are insoluble in water. Here, soluble ions are expressed with an (aq). and insoluble ions are expressed with an (S).

For example,

Reactant side,

Bacl2 – aqeuos – soluble in water

K2so4 – aqeuos – soluble in water

Products side,

Baso4 – solid – insoluble in water

2kCl – aqeuos – soluble in water

You know that, most of covalent compound and elements are insoluble in water.

What is covalent compound? – covalent compound is formed when two or more nonmetallic elements bonded to each other. this type of compound is called covalent compound.

Explain the Ionic equation

ionic equation is a one type of chemical equation in which aqeuos solution are represent as dissociate ions.

If you want to balance the ionic equation, then first you have to maintain number and atoms are same in both side of the reaction. then you can balance properly.

ionic equation is same as molecular equation, in case of ionic equation it is also expressed compound as molecules in ionic equation.

For example;

Ba(2+) + 2Cl(-) + 2k (+) + so4(-) – baso4 + 2k(+) + 2Cl(-)

What is Spectator ions? – in this complete ionic equation you can see that, ions are same and ions has same charge on both side (reactant side and product side) of the complete ionic equation. there are two ions are same on both side of ionic equation. it mean that, there are two spectator ions are present on both side of the ionic equation. these ions are called spectator ions. such as,

2Cl(-) – spectator ions

2k(+) – spectator ions

these are spectator ions. and it is present in this chemical equation.

In other words you can define of spectator ions is,

Spectator ions = same ions on both side of the complete chemical equation.

First, you identify in both side (reactant and products side) of the chemical ionic equation. and then cancel out from both side of chemical equation.

If you cancel spectator ions on both side from ionic equation then final equation is called net ionic equation,

Frequently Asked Question

1. What is difference between aqeuos and solid?

aqeuos solution – the solution which is formed by dissolving a substance in water is called aqeuos solution. You dissolve any substance in water you get aqeuos solution.

But not every substance is soluble in water. only polar compound are soluble in water. so it is also called polar covalent compound. non matel compound are not soluble in water.

For example,

Matel compound – salt, suger

Non matel compound – oil and petroleum

Solid – solid is that state of matter in which consistute particles are bonded with strong force of attraction.


  1. Shap, size, volume are fixed
  2. Compressibility is low
  3. Flexibility is also low
  4. It is not diffusion
  5. Melting point and boiling point are high.

2. What is difference between Ionisation and dissociation?

Ionisation, – if reactant compound is in non ionic form before dissolving in water but if it is dissolve in water then it will convert in the form of two different ions. this is called ionisation. you can easily understand with the following reaction,

  1. For example,

CH3COOH + h2O – CH3COO(-) + H3O(+)

(non ionic) ( ions)

2. For examples,

HCl + h2o – H (+) + Cl (-)

(Non ionic) (ions)

Dissociation – if reactant is in the form of ions before dissolving in water but if it is dissolve in water it will converted in the from of aqeuos solution. this is called dissociation. you can understand properly with the following reaction.

For example,

NaCl + h2O – Na(+) [aq] + Cl(-) [aq]

(ionic form) (aqeuos solution form)

3. What is complete ionic equation?

You know that, a complete ionic equation is one type of chemical equation in which the dissolved ionic compound are written in term of separated ions.

In case of ionic equation, ionic equation is a one type of chemical equation in which aqeuos solution are represent as dissociate ions. Or other words, the chemical formulas of aqeuos ionic compound is expressed in the term of dissociated ions. and it converted ionic form to aqeuos solution forms.

4. What is difference between atoms and ions?

atoms – it is smallest particles of an element which may or may not exist independently.

It is always neutral.

Ions – Any species that carries either positive or negative charge. it is formed by loss Or gain of electrons. there are two different types such as,

Cation – positive charge (+)

Anion – negative charge (-)
