In chemistry, neutralization is a chemical reaction in which an 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.
- New substances called SALTS and water are formed in neutralization reactions.
- For example, hydrochloric acid and sodium hydroxide solution react together to form water and sodium chloride solution. The H+ ions and OH– ions produce the water, and the Na+ ions and Cl– ions produce the sodium chloride, NaCl(aq).
