Question

To increase the pH value of a neutral solution, we should add

• A. an acid
• B. an acid salt
• C. an alkali
• D. a salt

Answer 1

The correct option is C

an alkali

Part 1 Explanation to the correct answer

Correct option is C:- an alkali

1. We should use an alkali to raise the pH of a neutral solution.
2. The pH of a neutral solution is $7.0$
3. The pH of a basic solution is more than $7.0$
4. The pH of a neutral solution rises when an alkali is added.
5. We should use acid to lower the pH of a neutral solution.

Therefore, To increase the pH value of a neutral solution, we should add option (c) an alkali
