Answer: Option C — a-ii, b-iii, c-i, d-iv
Detailed Solution
Baking soda is (ii), washing soda is (iii), gypsum is (i) and plaster of Paris is (iv). The correct matching is therefore a-ii, b-iii, c-i, d-iv, which is option C. In each of the other options at least one pair is wrong: option A joins washing soda to the formula of gypsum, and options B and D join baking soda to a wrong formula. Heating gypsum at about 373 K gives plaster of Paris, and baking soda is used to reduce acidity and to make cakes rise.
