Question

The pH of a solution is zero. The nature of the solution is

• A. Acidic
• B. Basic
• C. Neutral
• D. Amphoteric

Answer 1

The correct option is A

Acidic

The explanation of the correct option:

Option A is the correct option.

1. $pH$ is a scale used to measure the acidity and basicity of a solution at the temperature of $25°C$.
2. The $pH$ scale has values $0\text{to}14$ where the $pH$ range $0\text{to}7$ represents the acidic medium and $7\text{to}14$ represents the basic medium and only $7$ neutral solutions. This range works at temperature of $25°C$.
3. If the pH value of a solution is 0 it is considered to be a highly acidic solution.

The explanation for the incorrect options:

Option B:

1. The solution is considered to be basic in nature if it has a pH value of $8$ to $14$.

Option C:

1. The solution is considered to be neutral in nature if it has a pH value of $7$.

Option D:

1. Amphoteric substances are those substances that can act like both acid and base depending upon the reaction carried out.

Final Answer: The nature of the solution $(\mathrm{pH}=0)$ is highly acidic.
