Definition - What does Neutralisation mean?

Neutralisation is a process whereby a strong base and strong acid react with each other to yield a neutralized solution. When the strong base is added to the strong acid, its pH rises as the base reacts with the acid to form a neutral product. When acid is added to a base, its pH drops. When strong acids are neutralized by adding strong bases, the solution is left with less hydrogen ions. The solution is said to be neutral because it is neither basic nor acidic.

Petropedia explains Neutralisation

The chemical reaction which neutralizes acids and bases is known as Neutralisation. The output of the reaction involving a base and an acid is always water and salt and also involves a combination of hydroxide (OH-) and hydrogen (H+) ions that generate water.

The following are the names of the salts produced in Neutralisation:

  • Neutralising sulfuric acid results in sulfate as the salt.
  • Neutralising hydrochloric acid results in chloride as the salt.
  • Neutralising nitric acid results in nitrate as the salt.
The amount of base and acid needed is the amount which would give one mole of OH- and H+ respectively.
