`H_2CO_3_(aq) rarr 2H^+_(aq)+CO_3^(2-)_(aq)` ----(1)

`KOH_((aq)) rarr K^+_(aq)+OH^-_(aq)` -----(2)

This is a acid base reaction. KOH act as a base & `H_2CO_3` act as an acid.`H_2CO_3` gives two `H^+` ions. So we need `2OH^-` ions as well.

(1)+2*(2)

`H_2CO_3_(aq)+2KOH_(aq) rarr2H^+_(aq)+CO_3^(2-)_(aq)+2K^+_(aq)+2OH^-_(aq)`

`H_2CO_3_(aq)+2KOH_(aq) rarrCO_3^(2-)_(aq)+2K^+_(aq)+2H_2O_((l))`

In both sides K^+ và CO_3^(2-)...

`H_2CO_3_(aq)+2KOH_(aq) rarrCO_3^(2-)_(aq)+2K^+_(aq)+2H_2O_((l))`

In both sides K^+ và CO_3^(2-) ions remain same. So they will cancel out.

So the net ionic equation will be;

`2H^+_(aq)+2OH^(-)_(aq) rarr 2H_2O_((l))`
