Two solutions X and Y were found to have pH value of 4 and 10 respectively. The inference that can be drawn is
(a) X is a base and Y is an acid
(b) Both X and Y are acidic solutions
(c) X is an acid and Yis a base
(d) Both X and Y are bases

Correct Answer: (c) X is an acid and Yis a base

Explanation: Any solution having pH > 7 will be a base while the solution having pH < 7 will surely be an acid. Hence, it can be concluded that X is an acid (pH=4, i.e. < 7) and Yis a base (pH =10, i.e. > 7).
