Question:

Match the following and choose the correct option.

Column I Column II
(a) Citric acid (i) pH = 1.2
(b) Water (ii) pH = 2.2
(c) Hydrochloric acid (iii) pH = 10
(d) Milk of magnesia (iv) pH = 7
Options:

(a)-(ii), (b)-(iv), (c)-(iii), (d)-(i)

(a)-(iii), (b)-(iv), (c)-(i), (d)-(ii)

(a)-(i), (b)-(iv), (c)-(ii), (d)-(iii)

(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)

Correct Answer:

(a)-(ii), (b)-(iv), (c)-(i), (d)-(iii)

Explanation:

The correct answer is option 4. (a)-(ii), (b)-(iv), (c)-(i), (d)-(iii).

Acids have pH < 7 and base have pH > 7.

Neutral pH i.e., pH of water = 7

pH of citric acid = 2.2

pH of Hydrochloric acid (stronger) = 1.2

pH of Milk of magnesia [Mg(OH)2] = 10
