BOH is a weak base, molar concentration ...

`BOH` is a weak base, molar concentration of `BOH` that provides a `[OH]^(-)` of `1.5xx10^(-3) M[K_(b)(BOH)=1.5xx10^(-5) M]` is

A

`0.15 M`

B

`0.1515 M`

C

`0.0015 M`

D

`1.5xx10^(-5) M`

Text Solution

Verified by Experts

The correct Answer is:
A
`BOHhArrB^(+)+OH^(-)`
By Ostwald's dilution law, `[OH^(-)]=sqrt(K_(b)C)`
`1.5xx10^(-3)=1.5xx10^(-5)`
`C=0.15 M`
