Question

Which of the following substances are not used for the preparation of baking soda?

  1. Ammonium bicarbonate
  2. Calcium Carbonate
  3. Sodium carbonate
  4. Sodium chloride

hintHint:

Calcium is not an ingredient in the process of making baking soda.

The correct answer is: Calcium Carbonate


    • The chemical name of baking soda is sodium bicarbonate.
    • It is prepared as follows:
    NaCl + H2O + CO+ NHrightwards arrow NH4Cl + NaHCO3

    • On heating baking soda 
    NaHCO3 rightwards arrow Na2CO+ CO2 + H2O
    • Calcium carbonate is not used in the preparation of baking soda.
