Sulphuric acid (H2SO2) is a dibasic acid. It generated H+ ions when dissolved in water. In order to neutralize an acid, a base containing hydroxy ion (OH-) will be required.
NaOH, Ca(OH)2, KOH, etc. can be used to neutralize H2SO4.
If NaOH is used as a base, following reaction is initiated.
2NaOH + H2SO4 → Na2SO4 + H2O
(base) (acid) (salt)
