Concentration of H^+ ions in a solution ...

Concentration of `H^+` ions in a solution is `3.98 xx 10^-6` moles per Liter. Calculate the pH value of this solution.

A

6

B

5.8

C

5.4

D

5.9

Text Solution

Verified by Experts

The correct Answer is:
C
`pH=-"log"[H^+]`
`=-log(3.98 xx 10^-6)`
= -log 3.98 - log `10^-6`
`=-0.59+6=5.41`
