After 20 " mL of " 0.1 M `Ba(OH))_(2)` is mixed with 10 " mL of " 0.2 M `HClO_(4)`, the concentration of `overset(ɵ)(O)H` ions is

A

`2xx10^(-3)M`

B

`10^(-3)`M

C

0.066 M

D

`overset(ɵ)(O)H` ions are completely neutralised.

Text Solution

Verified by Experts

The correct Answer is:
C
`m" Eq of "overset(ɵ)(O)H=20xx0.1xx2=4mEq`
m" Eq of "`HClO_(4)(x=1)=10xx0.2xx1=2mEq`
m" Eq of "`overset(ɵ)(O)H` left`=4-2=2mEq`
Concentration or `N of overset(ɵ)(O)H=(2mEq)/(30mL)`
`=0.066N of overset(ɵ)(O)H`
`=0.066 M of overset(ɵ)(O)H`
