Answer: The compound X must be a base.

Explanation:

pH is the measure of acidity or alkalinity of a solution.

As we know, the pH scale ranges from 0 to 14, 0 to 6.9 being acidic, 7 being neutral and 7.1 to 14 being basic.

As the addition of the compound X increases the pH from 3.2 to 9.8 (which is greater than 7), it must be a basic compound. The addition of basic compound first neutralizes the acid and then make it basic.
