Neutralization (chemistry) - Wikipedia

In chemistry, ,neutralization, or neutralisation (see spelling differences) is a chemical reaction in which ,acid, and a base react quantitatively with each other. In a reaction in water, ,neutralization, results in there being no excess of hydrogen or hydroxide ions present in the solution. The pH of the neutralized solution depends on the ,acid, strength of the reactants.
