A 1.0 M with respect to each of the metal halide AX3, BX2 CX3 and DX2 is electrolysed using platinum electrodes. If The correct sequence in which the various metals are deposited at the cathode is
A.A, B, C, D
B.A, B, C✓ Correct
C.D, C, B, A
D.C, B, A
Explanation
The more the reduction potential, the more is the deposition of metals at cathode. Cations having E° value less than – 0.83 V ( reduction potential of H₂O) will not deposit from aqueous solution.
