Question

A solution has a pH value of 2. It can be concluded that the given solution is _______ in nature.

• A. strongly basic
• B. weakly basic
• C. strongly acidic
• D. weakly acidic

Answer 1

The correct option is C

strongly acidic

The basic and acidic nature of a solution is determined by measuring the hydrogen ion concentration present in it. This concentration can be measured by a pH scale. The table given below shows the approximate pH range of the acidic, basic and neutral solutions. $$\begin{array}{cc}\text{Type of solution}& \text{Approx. pH range}\\ \text{Weakly acidic}& \text{3 - 7}\\ \text{Strongly acidic}& \text{0 - 3}\\ \text{Neutral}& \text{7}\\ \text{Weakly basic}& \text{7 - 10}\\ \text{Strongly basic}& \text{10 - 14}\end{array}$$Since the pH value of the given solution is 2, the solution is strongly acidic.
