Common salt besides being used in kitchen can also be used as the raw material for makingi) Washing sodaii) Bleaching powderiii) Baking soda iv)Slaked lime A) (i) and (ii)B) (i),(ii) and (iv)C) (i) and (iii)D) (i),(iii) and (iv)

The correct answer is C) (i) and (iii).

Common salt, also known as sodium chloride (NaCl), can be used as the raw material for making washing soda (sodium carbonate, Na2CO3) and baking soda (sodium bicarbonate, NaHCO3).

(i) Washing soda: Sodium carbonate (washing soda) is commonly produced from the chemical reaction between common salt (sodium chloride) and limestone (calcium carbonate). The process involves several steps and the use of other chemicals, but common salt is one of the essential raw materials in its production.

(iii) Baking soda: Baking soda (sodium bicarbonate) can also be produced from common salt. The process involves several steps, including the reaction of common salt with ammonia and carbon dioxide. Baking soda is widely used in cooking, baking, and as a household cleaner.

Bleaching powder (calcium hypochlorite, Ca(ClO)2) and slaked lime (calcium hydroxide, Ca(OH)2) are not directly produced from common salt, so options (ii) and (iv) are incorrect.
