    Answer:

    Explanation:

    reduction potential of Ag+/Ag = 0.80 V

    the oxidation potential of Br-/Br2 = -1.066 V

    reduction potential of Na+/Na = 2.71 V

    reduction potential of 2H+/H2 = 0.00 V

    oxidation potential of 2F-/F2 = -2.87 V

    oxidation potential of 2H2O↔  O2 + 4H+  + 4e- = -1.23 V

    So,  at cathode reduction occurs so, here Ag(s) will form because it has high reduction potential.

    However, at anode oxidation occurs and , here the substance with high oxidation potential can oxidises easily so bromine will form.
