a)
At anode oxidation occurs
The anode reaction is:
Co (s) —> Co2+ (aq) + 2e-
b)
At cathode reduction occurs
The cathode reaction is:
Cu2+ (aq) + e- —> Cu+ (aq)
c)
The net reaction is:
Co(s) + 2 Cu2+(aq) -> Co2+(aq) + 2 Cu+(aq)
d)
electron in absorbed at Cu2+ electrode and given out at Co electrode
So,
In the external circuit, electrons migrate (from) the Co|Co2+ electrode (to) the Cu+|Cu2+ electrode.
e)
Anion flow opposite to electron to maintain charge neutrality
In the salt bridge, anions migrate (to) the Co|Co2+ compartment (to) the Cu+|Cu2+ compartment.
