Neutralization Reaction

Neutralization reaction is the reaction in which an acid reacts with the base to form salt and water after losing all the properties of both acid and base. They are always exothermic in nature as they produce the same amount of heat during the reaction.

For Example:

                HX (Acid) + BOH (Base) → BX (Salt) + H2O (Water)

In this reaction, H+ ion of the acid combines with the OH- ion of the base to give water.

                NaOH + HNO3 → NaNo3 + H2O

                Ca(OH)2 + 2HCl → CaCl­2 + 2H2O

Application of Neutralization Reaction

  • Neutralization reaction controls the pH of the soil, so farmers use quicklime or calcium oxide (CaO) to remove the acidity of the soil.
  • Neutralization is used to manufacture antacid, in form of magnesium hydroxide which helps neutralize the stomach’s acidic environment.

  1. The reaction in which acid reacts with the base in which the properties of both acid and salt are destroyed or neutralized to form salt and water is called neutralization reaction.
  2. Neutralization reactions are exothermic in nature that releases heat energy in the surroundings.
  3. Bees stings are acidic in nature as they spew formic acid in the skin, so a household remedy for such sting is sodium bicarbonate or baking soda. They neutralize the formic acid of the skin after the sting.
  4. The sting of asp is mild basic, so a household remedy for it is vinegar or acetic acid. The treatment using vinegar or acetic acid minimizes painful stings by neutralization process.
