Homework Answers
1)
a)
At anode oxidation occurs
The anode reaction is:
Pb (s) —> Pb2+ (aq) + 2e-
b)
At cathode reduction occurs
The cathode reaction is:
F2 (g) + 2e- —> 2F- (aq)
c)
electron in absorbed at F2 electrode and given out at Pb electrode
So,
In the external circuit, electrons migrate (from) the Pb|Pb2+ electrode (to) the F-|F2 electrode.
d)
Anion flow opposite to electron to maintain charge neutrality
In the salt bridge, anions migrate (from) the F-|F2 compartment (to) the Pb|Pb2+ compartment.
