MHT CET Chemistry question
Which of the following metals will be deposited first when a solution containing 0.1 mol/litre of each of AgNO, Ca(NO) and Mg(NO) is electrolyzed by using inert electrodes? It is given that = +0.80 V, = 0.34 V, = -0.25 V and = -2.38 V.
Answer: (A)
Solution
During electrolysis the ion with the highest reduction potential is discharged first at the cathode; Ag (+0.80
