pH of Ba`(OH)_(2)` Ssolution is 12. Its solubility product is :

A

`10^(-6) M^(3) `

B

` 4 xx 10^(-6) M^(3) `

C

` 0.5 xx 10 ^(-7) M^(3)`

D

` 5xx 10 ^(-7) M^(3)`

Text Solution

Verified by Experts

The correct Answer is:
D
`pH =12 rArr [OH^(-) ] =10 ^(_2) =2S rArr S =5 xx 10 ^(-3)`
` Ksp = 4s^(3) =5 xx 10 ^(-7) `
