Question

preparation of baking soda

Answer 1

Explanation:

Baking soda is common name of compound made up of sodium , hydrogen carbon and oxygen elements with molecular formula of $NaHCO_3$

1. It is prepared by the reacting sodium carbonate with water and carbon dioxide gas.

$Na_2CO_3+H_2O+CO_2\rightarrow 2NaHCO_3$

2. It can also be prepared by reacting carbon dioxide and sodium hydroxide.

$CO_2+NaOH\rightarrow NaHCO_3$

Answer 2

In industries, Solvay process is used to produce sodium bicarbonate or baking soda.

Explanation:

• The chemical name for baking soda is sodium bicarbonate and the chemical formula is Na2CO3.
• The raw materials used to produce sodium bicarbonate are concentrated solutions of carbon dioxide, water, ammonia, and brine solution. By allowing the chemical reaction of carbon dioxide (CO2) + water (H2O) + ammonia (NH3) + sodium ion (Na+) --> sodium hydrogen bicarbonate (NaHCO3) + ammonium cation (NH+4) are obtained.
• Further reaction of sodium hydrogen bicarbonate (NaHCO3) produces sodium bicarbonate (Na2CO3) + carbon dioxide (CO2) + water (H2O).
