Explanation:
An ionic equation is an equation in which the given reactant species or electrolytes are written in the form of dissociated ions in the presence of a solution.
For example, [tex]HCl + HCOONa \rightarrow HCOOH + NaCl[/tex]
The ionic equation for the same will be as follows.
[tex]H^{+}(aq) + Cl^{-}(aq) + HCOO^{-}(aq) + Na^{+} \rightarrow HCOOH(aq) + Na^{+}(aq) + Cl^{-}(aq)[/tex]
Therefore, cancelling common ions from, that is, [tex]Na^{+}(aq)[/tex] and [tex]Cl^{-}(aq)[/tex] from both sides we get the net ionic equation as follows.
[tex]H^{+}(aq) + HCOO^{-}(aq) \rightarrow HCOOH(aq)[/tex]
