Which of the following statement is true for the electrochemical Daniell cell ?

A

Electrons flow from copper electrode to zinc electrode

B

Current flows from zinc electrode to copper electrode

C

Cations move toward copper electrode which is cathode

D

Cations move toward zinc electrode

Text Solution

Verified by Experts

The correct Answer is:
C
In Daniel cell copper rod acts as cathode so there cations move towards copper electrode and reduction take place on copper rod.
