Redox Reactions by Transfer of Electrons at a DistanceIn all redox reactions, electrons are transferred from the reducing agent to the oxidising agent.When the reducing and oxidising agents are mixed together as in the previous reactions, the transfer of…

Redox reaction in the displacement of metals from its salt solutionGenerally, metals are good electron donors and therefore are good reducing agents. However, different metals have different strength as reducing agents.The strength of metals as reducing …

Displacement of Halogen from Halide SolutionGenerally, halogens are good electron acceptors and therefore are good oxidising agents.(a) When going down Group 17, the size of the halogen atoms increases. The nucleus is further away from the outermost occu…

Changing of iron(II) ions to iron(III) ions and vice versaIron exhibits two oxidation numbers (a) +2 as iron(II) ion, Fe2+ (b) +3 as iron(III) ion, Fe3+An aqueous solution containing iron(II) ions, Fe2+ is pale green in colour, whereas that containing ir…
