Describe how sodium hydrogen carbonate (baking soda) is produced on a large scale. Write equation of the reactions involved.

Academic Chemistry NCERT Class 10

Baking soda is produced large scale by reacting a cold and concentrated solution of sodium chloride called brine with ammonia and carbon dioxide.

The reaction is given below:

$NaCl + NH_3 + H_2O + CO_2 → NaHCO_3 + NH_4Cl$
