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

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

A

`3.98 xx 10^(8)`

B

`3.88 xx 10^(6)`

C

`3.68 xx 10^(-6)`

D

`3.98 xx 10^(-6)`

Text Solution

Verified by Experts

The correct Answer is:
D
`pH=5.4 `
`-log H^(+)=5.4 `
`log H^(+)=-5.4 =-5-0.4 `
`=-5-1+1-0.4`
`=-6+0.6=bar(6).6`
`H^(+)=-bar(6).6=3.98xx10^(-6)`
