MHT CET Chemistry question
A solution containing one mole per litre of each , , , is being electrolyzed by using inert electrodes. The value of reduction potentials are Ag/Ag = +0.80, Hg/Hg = 0.79, Cu/Cu = +0.34, Mg/Mg = −2.7. With increasing voltage, the sequence of deposition of metals on the cathode will be
Answer: (B)
Solution
The ion with the highest reduction potential is discharged first at the cathode, so the order follows +0.80 (Ag),
