Question
Which of the following steyements is true for the electrochemical Daniel cell?
Options
A.Electrons flow copper electrode to zinc electrode
B.Current flows from zinc electrode to copper electrode
C.Cations move toward copper electrode
D.Cations move toward zinc electrode
Solution
Daniel cell is an electrochemical in which Cu acts as cathode and Zn acts as an anode. In Daniel cell,
(i) Electrons flow from Zn (anode) vto Cu (cathode).(ii) Current flows from Cu (Cathode) to Zn (anode).(iii) Cu2+ ions (cations) move towards Cu (cathode) and accumulated as Cu metal.
(i) Electrons flow from Zn (anode) vto Cu (cathode).(ii) Current flows from Cu (Cathode) to Zn (anode).(iii) Cu2+ ions (cations) move towards Cu (cathode) and accumulated as Cu metal.
