Question

A compound ‘X’ of sodium is used as an antacid and it decomposes on strong heating.

(i) Name the compound ‘X’ and give its chemical formula.

(ii) Write a balanced chemical equation to represent the decomposition of ‘X’.

(iii) Give one use of compound ‘X’ besides an antacid.​

Answer 1

1.X is NaHCO3(baking soda)

3. it is used to make baking power

baking power= backing soda and tartaric acid

Answer 2

Explanation:

(i) Sodium hydrogen carbonate (Commonly known as baking soda) is used as an antacid. The chemical formula is $NaHCO_3$.

(ii) The decomposition reaction is:

$2NaHCO_3_{(s)}\rightarrow Na_2CO_3_{(s)}+CO_2{(g)}+H_2O_{(g)}$

(iii) Sodium bicarbonate is used in fire extinguisher as it is a source of carbon dioxide.
