Text Solution

Verified by Experts

The salt used to make tasty and crispy pakoras is baking soda or sodium hydrogen carbonate `(NaHCO_(3))`.
Sodium hydrogen carbonate is produced by reacting a cold and concentrated solution of sodium chloride (called brine) with ammonia and carbon dioxide.
`underset("Chloride")underset("Sodium")(NaCl) + underset("Ammonia")(NH_(3)) + H_(2)O + CO_(2) rarr underset("Hydrogen carbonate")underset("Sodium")(NaHCO_(3)) + underset("Chloride")underset("Ammonium")(NH_(4)Cl)`
uses of baking soda :
(i) It is used for making baking powder which is used for baking bread, cakes etc.
(ii) It is used as an ingredient in antacids to reduce the effect of excess acid n the stomach.
