# Write the net ionic equation for {eq}Ba(NO_3)_2 {/eq} and {eq}NiSO_4 {/eq}.

## Question:

Write the net ionic equation for {eq}Ba(NO_3)_2 {/eq} and {eq}NiSO_4 {/eq}.

## Ionic Equation:

Ionic equation refers to the depiction for the ionic form of different molecules which participates in the various chemical reactions. It is applicable for single displacement reaction or double displacement reaction.

When barium nitrate reacts with nickel sulfate then it gives nickel nitrate and barium sulfate. Its chemical equation can be written as,

{eq}BaS{O_4}\left( {aq} \right) + NiS{O_4}\left( {aq} \right) \to Ni{\left( {N{O_3}} \right)_2} + BaS{O_4}\left( s \right) {/eq},

The ionic equation can be written as,

{eq}Ba_2^ + \left( {aq} \right) + 2NO_3^ - \left( {aq} \right) + N{i^{2 + }}\left( {aq} \right) + SO_4^{2 - }\left( {aq} \right) \to N{i^{2 + }}\left( {aq} \right) + 2NO_3^ - \left( {aq} \right) + BaS{O_4}\left( s \right) {/eq},

Nickel ion and nitrate ion will be canceled

The net ionic equation can be expressed as,

{eq}B{a^{2 + }}\left( {aq} \right) + SO_4^{2 - }\left( {aq} \right) \to BaS{O_4}\left( s \right) {/eq}
