1.

b identify the following reactions as either oxidation orreduction:(ifi) Fe3e> Fe2+

Answer»

Oxidation is loss of electronsReduction is gain of electrons

(I) O + 2e- ==> O2- In this oxygen is gaining electrons so its a reduction reaction

(2) K - e- ==> K+ In this potassium is losing electrons so its a oxidation reaction.

(3) Fe3+ + e- ==> Fe2+ In this iron is gaining electrons so its a reduction reaction
