A weak acid `HA` and a weak base `BOH` are having same value of dissociation constants . If `pH` of `0.01M HA` is 4, then `pH` of `0.01 M BOH` will be

A

3

B

4

C

10

D

11

Text Solution

Verified by Experts

The correct Answer is:
2
`C_(11)^(+2)H_(22)O_(11)rarrCO_(2)`
`rArrpH` of Acid`=pOH` of base `=14-pH` of base `" "rArrpOH ` cf base `=14-4=10`
