Question

formation & uses of baking soda

Answer 1

Preparation of Baking soda:
Solvay process is used for the production of sodium bicarbonate and sodium carbonate industrially. In this process carbon dioxide, water, ammonia and brine solution in its concentrated form, are used as raw materials. This process is used mainly as it is inexpensive and less number of raw materials is used to produce necessary chemicals. The important chemical reaction that is used in the production of baking soda and sodium carbonate is:

CO2+H2O+NH3+Na+→NaHCO3+NH+4

NaHCO3→Na2CO3+CO2+H2O

Uses of baking soda:
Reduces the acidity in the stomach
Acts as an antacid which is used to treat stomach upset and indigestion
Used in the process of washing as a water softener
Due to the formation of soapy foam, it is used in fire extinguishers
Removes the dirt off materials without damaging the properties of the material
Acts as a pesticide
Used in baking industries as carbon dioxide is generated (due to decomposition of NaHCO3)) which helps in the raising of the dough
It is used in ear drops, cosmetics, and personal care products
It is used as a neutralizer to neutralize the effect of acid
