Hydrogen ion concentration in mol//L in ...

Hydrogen ion concentration in `mol//L` in a solution of `pH=5.4` will be:

A

`3.98xx10^(8)`

B

`3.88xx10^(6)`

C

`3.68xx10^(8)`

D

`3.98xx10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
D
`pH=5.4= -log[H^(+)]`
`:. [H^(+)] = anti log (-5.4)`
`=3.98xx10^(-6)`
