A) Electrons flow from 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
Correct Answer: C
Solution :
In Daniell cell, following reaction occurs. \[Zn+C{{u}^{2+}}\xrightarrow[{}]{{}}Z{{n}^{2+}}+Cu\] At cathode \[C{{u}^{2+}}+2{{e}^{-}}\xrightarrow[{}]{{}}Cu\] At anode \[Zn\xrightarrow[{}]{{}}Z{{n}^{2+}}+2{{e}^{-}}\] \[\therefore \] Electrons moves from anode (Zn) to cathode (Cu) and electricity flows from Cu to Zn. Here, cations move towards cathode copper electrode.
