Question

If $pH$ of the solution is $13$, means that it is

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

Answer 1

The correct option is D

strongly basic

Explanation of correct option:

The correct option is D:

1. At $25°C$, the $pH$ scale has the value of $0to14$ where $0$ represents the most acidic, $7$ represents neutral, and $14$ represents the most basic medium.
2. The $13$ is more closer to $14$ so it represents the strongly basic solution or medium.
3. The $pH$ is determined at the temperature of $25°C$.

Explanation of incorrect options:

Option A:

• If the $pH$ is less than $7$ and greater than $4$ so it represents the weekly acidic solution.

Option B:

• If the $pH$ is greater than $7$ and less than $9$ so it represents the weekly basic solution.

Option C:

• If the $pH$ value is closer to $0$, it represents a strongly acidic solution.

Final Answer: If $pH$ of the solution is $13$, means that it is strongly basic.
