Neutralisation reaction is a chemical reaction in which an acid and a base react to form salt & water.When strong acids and strong bases react, the products are salt and water. The acid and base neutralize each other, so the solution will be neutral having pH=7 and the ions that are formed will not react with the water.Depending on the solubility of the salt, it may remain in ionized form in the solution or it may precipitate out of solution.
