The pH of Ba(OH)(2) solution is 13. The ...

The `pH` of `Ba(OH)_(2)` solution is `13`. The number millimoles of `Ba(OH)_(2)` present in `10 ml` of solution would be

A

`1.00`

B

`0.50`

C

`10.00`

D

`15.00`

Text Solution

Verified by Experts

The correct Answer is:
B
`[OH^(-)]=0.1` and conc. of `Ba(OH)_(2)=(0.1)/(2)`
`:.` The no. of milimoles of `Ba(OH)_(2)` present in `10 ml` soultion `=(0.1)/(2)xx10xx10^(-3)xx10^(3)=0.5`
