Aqueous solution of AgNO3 is electrolyse...

Aqueous solution of `AgNO_3` is electrolysed using inert electrodes. At the end of electrolysis

A

pH of the solution increases

B

pH of the solution decreases

C

pH of the solution remains unchanged

D

pH of the solution becomes 14

Text Solution

Verified by Experts

The correct Answer is:
B
at cathode `: Ag^(+) + e^(-) to Ag ` , at anode `: 2H_2O to O_2 + 4H^(+) + 4e^(-)`
`[H^(+)]uarr [pH]^darr pH = log""(1)/([H^(+)])`
