electrolysis of KBr gives Br2 at anode but KF does not give F2 Why - Chemistry - Electrochemistry

Question

electrolysis of KBr gives Br2 at anode but KF does
not give F2 Why?

Anuradha Puri · Accepted Answer

Higher is the oxidation potential, easier to oxidize a specie The
oxidation potential of Br- is higher than water whereas
the oxidation potential of F- is lower than water

Therefore, in aq solution of KBr, Br- ions are oxidized
to Br2 in preference to H2O Whereas, in aq
solution of KF, H2O is oxidized in preference to
F- Thus, oxidation of H2O at anode gives
O2 and no F2 is produced

electrolysis of KBr gives Br2 at anode but KF does not give F2. Why?
