A neutralization reaction is when an acid and a base react to form water and a salt and involves the combination of H+ ions and OH- ions to generate water. The neutralization of a strong acid and strong base has a pH equal to 7.
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).
