Step 1

A chemical equation in which the electrolytes of aqueous solution are represented as dissociated ions is known as ionic equation.

The net ionic equation for the reaction is the reaction in which only participated species are mentioned.

Step 2

For the first reaction the net ionic equation will be represented as follows:

HSO, (ag)+2NaOH (аq) —> Na, SO, (ag)-2н,0(1)
2H (аq)+20H (aq) —> 2H,0(1)
