The hydrogen ion concentration of 0.001 ...

The hydrogen ion concentration of `0.001 M NaOH` solution is

A

`1xx10^(-2) mol//litre`

B

`1xx10^(-11) mol//litre`

C

`1xx10^(-14) mol//litre`

D

`1xx10^(-12) mol//litre`

Text Solution

Verified by Experts

The correct Answer is:
B
`0.001 M NaOH` means `[OH^(-)]=10^(-3)`, `pOH=3`
`pH+pOH=14`, `pH=14-3`
`pH=11` , `[H^(+)]=10^(-11) "mole"-litre^(-1)`
