Question

Baking soda is a/an:
A.Acidic substance
B.Basic substance
C.Neutral substance
D.None of those

Answer 1

:Hint: Baking soda is the common name for sodium bicarbonate $\text{Na}\left( \text{HC}{{\text{O}}_{\text{3}}} \right)$ and is formed by the reaction of a strong base and a weak acid.

Complete step by step answer:
When a solution of sodium hydroxide reacts with lime water or a solution containing carbon dioxide dissolved in water then it results in the formation of baking soda or sodium hydrogen carbonate or sodium bicarbonate. When sodium bicarbonate is dissolved in water then it results in the liberation of the sodium cations and the hydroxide anions which turns the solution basic. The weak carbonic acid on the other hand does not have any influence on the pH of the solution.

Hence, the correct answer is option B.

Note:
The baking soda is highly used in cooking due to its ability to release carbon dioxide when it reacts with water. Hence this levitates the substance and gives a porous structure.
Baking soda has many other uses. It is used to relieve heartburn which is also known as acid reflux. This is due to its mildly basic nature. Baking soda solution can be used as a mouthwash. It reaches every corner of the mouth and hence is good as a mouthwash.
Baking soda can relieve the pain of canker sores which are painful ulcers in the mouth. Baking soda is also used to whiten the teeth and also as a natural deodorizer.
