JEE Main Chemistry question
A solution containing one mole per litre of each of , , and is being electrolysed using inert electrodes. The standard (reduction) electrode potentials in volts are , , , . With increasing voltage, the sequence of deposition of metals on the cathode will be
Answer: (A)
Solution
A cation with the highest reduction potential is deposited first as voltage is increased, so the order of deposition follows decreasing : Ag (0.80) > Hg (0.79) > Cu (0.34). ,
