Write the preparation of sodium bicarbonate with help of a chemical equation and also write its two uses.

Hint: We know that Baking soda is chemically called sodium bicarbonate. It is represented as $NaHC{{O}_{3}}$ . Its physical properties are responsible for such a wide variety of applications. Baking soda is a mild alkali.

Complete step by step answer:
-Baking soda is an effective and kid-safe household product that can be used on everything from kitchen drains to diaper rashes. Baking soda has an incredible power to remove odor. It can be used to remove odor from ashtrays, shoes, cat boxes, cloth diaper pails. It can also be used in laundry to help get rid of smells. It is also used as a stain remover. When combined with vinegar, it pulls stains out of carpets to cloth diapers.
Sometimes, baking soda is used as a scrubber since it is non-toxic and does not scratch surfaces. When baking soda is poured into the drain, the foaming action cleans the pipes. -Natural alternative for shampoo and body wash. -Natural skin soother is used to treat itchy skin conditions ranging from bug bites and windburn to diaper rash and eczema.
Application of sodium bicarbonate are:
For making baking powder : Baking powder is a mixture of starch, baking soda (sodium bicarbonate ) and a mild edible acid (e.g. tartaric acid).
$NaHC{{O}_{3}}+{{H}^{+}}\xrightarrow{{}}C{{O}_{2}}+{{H}_{2}}O+Sodium\text{ }salt\text{ }of\text{ }acid$
Baking powder is used in baking cakes, breads etc.
The \[C{{O}_{2}}~\] produced during the reaction helps in making the cake or bread spongy. Sodium carbonate is alkaline and is thus an ingredient in preparing antacids. It neutralizes the excess acidity in the stomach. It is used in the fire extinguisher.

Note:
Remember that Baking soda can be prepared in various methods. Prepared by reacting concentrated solutions of sodium chloride with carbon dioxide and ammonia. It is sparingly soluble in water. Prepared by treating washing soda with carbon dioxide and water. Prepared by treating sodium hydroxide and carbon dioxide.
