Question

1. Sodium carbonate is formed when carbon dioxide is passed through an aqueous solution
of sodium hydroxide (Sodium carbonate = washing soda)
Chemical equation of the reaction 2NaOH + CO, → Na CO, + HO
2. Sodium bicarbonate is formed on passing CO, through an aqueous solution of sodium
carbonate. (sodium bicarbonate = baking soda)
Chemical equation of the reaction Na, C0, + H2O + CO2 → 2NaHCO,
a. Write down the equation of the chemical reaction taking place between water and
carbon dioxide in the above experiment.
b. Write down the equation of the chemical reaction taking place on putting limewater
in the gas jar of CO,​
