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 electrons occurs quickly and cannot be detected. However, when the reducing and oxidising agents are separated … [Read more...] about Redox Reactions by Transfer of Electrons at a Distance
What is oxidation and reduction reaction?
Redox reaction in the displacement of metals from its salt solution
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 agents can be compared by using the electrochemical series. The electrochemical series lists metals according to … [Read more...] about Redox reaction in the displacement of metals from its salt solution
Displacement of Halogen From Halide Solution
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 occupied shell. (b) Hence, the electronegativity of halogens or their ability to accept electrons to form … [Read more...] about Displacement of Halogen From Halide Solution
Changing of iron(II) ions to iron(III) ions and vice versa
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 iron(III) ions, Fe3+ is yellow/yellowish-brown/ brown in colour. Changing iron(II) ions to iron(III) ions is an … [Read more...] about Changing of iron(II) ions to iron(III) ions and vice versa
What is a redox reaction?
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 simultaneously. Therefore, redox reaction is also known as oxidation-reduction reaction. It is … [Read more...] about What is a redox reaction?
