Which salt is produced when h2so4 reacts with naoh?

The type of chemical reaction that occurs when H2SO4 react with NaOH is neutralization reaction; in this reaction salt and water are always the products of the reaction. The balanced equation for the chemical reaction is given below:

H2SO4 + 2NaOH = 2H2O + Na2SO4.

The equation implies that, two molecules of NaOH react with one molecule of H2SO4 to give two molecules of water and one molecule of Na2SO4.

Thus, the salt that is produced from the reaction is disodium sulphate, Na2SO4.
