"Given below are the pH values of 4 different liquids:- 7.0, 14.0, 4.0, 2.0 . Which of these could be that of :

a) lemon juice


b) distilled water


c) sodium hydroxide solution


d)tomato juice."

(a) Lemon juice: pH = 2.0.


Lemon juice is acidic in nature, hence its pH should be less than 7.0.


(b) Distilled water: pH = 7.0


Distilled water is neutral in nature; hence its pH should be equal to 7.


(c) Sodium hydroxide solution: pH = 14.0.


Sodium hydroxide solution is basic in nature; hence its pH should be greater than 7.


(d) Tomato juice: pH = 4.0.


Tomato juice is acidic in nature; hence its pH should be less than 7.
