Abstract Aiming at the problem that the phenomenon of Fe2+ oxidation experiment is not obvious in the textbooks, the Fe2+ oxidation experiment is improved. The zinc sheet is cut into fine zinc wires, and through the reaction of zinc wire with ferrous salt solution, after a period of reaction, the zinc wires are attracted by a magnet, the zinc wires can be attracted by the magnet, it proves that Fe2+ is reduced to iron element, which reflects the oxidizability of Fe2+.
