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

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^(-6)`

D

`3.98xx10^(-6)`

Text Solution

Verified by Experts

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