Question

Which of the following is NOT the use of baking soda in the kitchen?

A.

For food colouring

B.

In fire extinguishers

C.

As a leavening agent

D.

As an ingredient in antacids

Correct option is A

The correct answer is: (a) For food colouring

Explanation:

  • Baking soda (chemical name: sodium bicarbonate, NaHCO₃) is not used for food colouring.

  • It is widely used in the kitchen as a leavening agent in baking (helps dough rise), in antacids to relieve acidity, and even in fire extinguishers due to its ability to release CO₂ when heated.

  • However, food colouring requires dyes or pigments, not baking soda.

Information Booster:

  • Baking soda reacts with acids like vinegar or lemon juice to release carbon dioxide (CO₂).

  • It is commonly used in baking cakes, muffins, and bread.

  • Acts as a fire suppressant by releasing CO₂ to smother flames.

  • Used in antacids to neutralize excess stomach acid.

  • It has mild abrasive and deodorizing properties for cleaning as well.
