The pH of a solution is 6. Sufficient amount of acid is added to decrease the pH to 2. The increase in hydrogen ion concentration is

A

three times

B

hundred times

C

thousand times

D

ten thousand times.

Text Solution

Verified by Experts

The correct Answer is:
D
pH =6 means `[H^+]=10^(-6), pH ="2 means "[H^+]`
Hence increase in `H^+` conc. `=10^(-4)` times =ten thousands times.
