Here is the correct matching of List-I (Trade Name) with List-II (Chemical Name):
A. Bleaching powder → 3. Calcium oxychloride
B. Baking soda → 1. Sodium bicarbonate
C. Washing soda → 2. Sodium carbonate, 10 water
D. Plaster of Paris → 4. Calcium sulphate, 1/2 water
InformationBooster:
Bleaching powder is widely used in water treatment plants for disinfection. Bleaching powder is chemically known as calcium oxychloride (Ca(OCl)₂).
Baking soda acts as a leavening agent in baking and can neutralize acidic odors. Baking soda is sodium bicarbonate (NaHCO₃), a common household chemical used in baking, cleaning, and neutralizing acids.
Washing soda is effective in removing stains and softening hard water. Washing soda is chemically known as sodium carbonate decahydrate (Na₂CO₃·10H₂O). It is used as a cleaning agent and in water softening.
Plaster of Paris sets quickly when mixed with water, forming a hard structure, which is useful in orthopedic casts and sculptures. Plaster of Paris is calcium sulfate hemihydrate (CaSO₄·0.5H₂O), used in construction and for making casts and molds.
