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…

What is a redox reaction?Many processes that occur around us are redox reactions. These include combustion, rusting, photosynthesis, respiration and decomposition.Redox reactions are chemical reactions involving oxidation and reduction occurring simultan…
