What is meant by the term neutralization?
Nadusha1986 [10]

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).

So basically, the change in color effects the amount of cations in the solution making it a physical change rather than a chemical one, defying the law of conservation of mass! I hope this helped! (The only time the change in color affects the amount of cations is in the Alkaline Earth Metals)
