Question

1. define neutralization reaction and give a real - life example.

Explanation:

A neutralization reaction is a chemical reaction between an acid and a base, resulting in the formation of a salt and water. In real - life, antacids (a base) are used to neutralize excess stomach acid. For example, when we take an antacid like calcium carbonate ($CaCO_3$) to relieve heartburn caused by too much hydrochloric acid ($HCl$) in the stomach, the reaction is $CaCO_3 + 2HCl=CaCl_2 + H_2O+CO_2$. Here, the acid and base react to form a salt ($CaCl_2$), water, and carbon dioxide.

Answer:

A neutralization reaction is a chemical reaction between an acid and a base to form a salt and water. A real - life example is the use of antacids to neutralize stomach acid.
