When acid and base react together they form salt and water.This reaction is known as Neutralization Reaction. ForExample HCl+NaOH ---------> NaCl + H2O HCl is acid while NaOH is a base, when they react with eachother they form NaCl, that is a salt (table salt) These reactions are also reversible reactions.
