In the neutralisation between sulphuric acid and potash, identify spectator ions.

Explanation

The molecular equation is `H_(2)SO_(4) + 2KOH rarr K_(2)SO_(4) + 2H_(2)O`
The ionic equation is `2H^(+) + SO_(4)^(2-) + 2OH^(-) rarr 2K^(+) + 2SO_(4)^(2-) + 2H_(2)O`
The spectator ions in the given reaction are `SO_(4)^(2-)` and `K^(+)`.
