Answer 1

Answer:

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

Example – 1: When Sodium hydroxide is added to hydrochloric acid. Sodium chloride and water are formed.

NaOH+HCl⟶NaCl+H

Answer 2

Answer:

A reaction in which an acid and base react with each other to give a salt and water is termed as neutralization reaction. In this reaction, energy is evolved in the form of heat. For example: NAOH+HCl→NaCl+H2O(base)(Acid)(Salt)(Water)
