Which among the following solutions has pH value more than 7?
- ABuffer solution
- BBasic solution
- CAcidic solution
- DNeutral solution
- ENone of the above / More than one of the above
Show answer and explanation
Correct answer: (b) Basic solution
Explanation
The pH scale runs from 0 to 14 and measures the concentration of hydrogen ions (H⁺) in a solution.
A basic (alkaline) solution has a pH greater than 7; it turns red litmus blue.
An acidic solution has pH less than 7, while neutral water has pH = 7.
