Which of the following are correct?

Options

A. Chloride liberates `Cl_2` but `O_2` is also liberated as the solution is diluted which is due to over voltage.
B. Soluble iodides always liberate iodine at anode
C. Water is reduced in preference to cations having more negative reduction potential than -0.828V
D. Cation having less negative potential than 0.828 V are reduced in preference to water.

Answer

A, B, C, D

Explanation

A) Chloride liberates `Cl_2` but `O_2` is also liberated as the solution is diluted which is due to over coltage .
B) Soluble iodides always liberate iodine at anode
C) Water is reduced in preference to cations having more negative reduction potential than 0.828 V
D) Cation having less negative potential than -0.828 V are reduced in preference to water .
