The interaction of NaOH and H2SO4 is a neutralization reaction, i.e. NaOH is a strong alkali that is neutralized by the acid H2SO4 and forms salt and water
2NaOH + H2SO4 = Na2SO4 + 2H2O
Since both substances are transparent, no visible changes will occur during the reaction.
In this case, the indicator phenolphthalein is added to NaOH, which stains the alkaline medium pink, and when sulfuric acid is added, the solution provides, which indicates a neutralization reaction.
