Answer 1

Answer #1

a)

At anode oxidation occurs

The anode reaction is:

2Br-(aq) —> Br2 (l) + 2e-

b)

At cathode reduction occurs

The cathode reaction is:

Cl2(g) + 2e- —> 2Cl- (aq)

c)

electron are absorbed at Cl2 electrode and given out at Br2 electrode

So,

In the external circuit, electrons migrate (from) the Br-|Br2 electrode (to) the Cl-|Cl2 electrode.

d)

Anion flow opposite to electron to maintain charge neutrality

In the salt bridge, anions migrate (to) the Br-|Br2 compartment (from) the Cl-|Cl2 compartment.
