Witch acid and base react in the formation of salt sodium chloride

The acid and base which react in the formation of salt sodium chloride are hydrochloric acid and sodium hydroxide.

Hydrochloric acid (HCl) is very strong and corrosive and is generally used for industrial purposes. Sodium hydroxide (NaOh), on the other hand, is a white, strong, chemical base used for paper production, detergents, soaps, etc.

Here is the complete balanced chemical reaction of how salt sodium chloride is formed:

HCl + NaOH = NaCl + H2O
