The two aqueous solutions, A (AgNO3) and...

The two aqueous solutions, `A (AgNO_3)` and `B (LiCI)`, were electrolysed using Pt electrodes. The `pH` of the resulting solutions will.

A

increase in A and decrease B

B

decreases in both

C

increase in both

D

decreases in A and increase B.

Text Solution

Verified by Experts

The correct Answer is:
D

`AgNO_(3)` At cathode:
`Ag^(+)+e^(-)toAg(s)`
At anode:
`2H_(2)OtoO_(2)+4H^(+)+4e^(-)`
`therefore` at cathode pH will increase.
