Common salt besides being used in kitchen can also be used asthe raw material for making(i) washing soda(ii) bleaching powder(iii) 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 (b) (i), (ii) and (iv).

Here's why:

(i) Washing soda: Common salt (sodium chloride) is used in the Solvay process to produce sodium carbonate, also known as washing soda.

(ii) Bleaching powder: Common salt is used in the manufacturing of chlorine, which is a key component in the production of bleaching powder.

(iv) Slaked lime: Common salt is used in the production of chlorine and hydrogen gases. When chlorine is treated with water (H2O), it produces hydrochloric acid and hypochlorous acid. The hypochlorous acid then reacts with lime (Ca(OH)2) to form bleaching powder (CaOCl2), also known as slaked lime.

(iii) Baking soda: Common salt is not used in the production of baking soda. Baking soda is sodium bicarbonate, which is produced from a reaction between carbon dioxide and soda ash (sodium carbonate). Soda ash can be produced from common salt, but the process does not involve common salt directly producing baking soda.
