Question
A current of 2.68 A is passed for one hour through an aqueous solution of CuSO4 using copper electrodes. Select the correct statement(s) from the following :
Options
A.increase in mass of cathode = 3.174 g
B.decrease in mass of anode = 3.174 g
C.no change in masses of electrodes
D.the ratio between the change of masses of cathode and anode is 1 : 2.
Solution
At Cathode :
Cu2+ + 2e- → Cu(s)
At Anode
Cu (s) → Cu2+ + 2e-
Increase in mass of cathode = decrease in mass of Anode =
= 3.174 g.
Cu2+ + 2e- → Cu(s)
At Anode
Cu (s) → Cu2+ + 2e-
Increase in mass of cathode = decrease in mass of Anode =
= 3.174 g. Create a free account to view solution
