    oxidation and reduction adalah tajuk sambungan dr electrochemistry...boleh buat ulangkaji tajuk electrochemistry terus bersambung ke tajuk redox
    first thing yang kena tahu ialah definition of redox based on 4 perkara ..loss or gain (oxygen,hydrogen,electron) and oxidation no
    2nd: kene tahu contoh...ade 4 cnth yang selalu ditanya dlm exam,: changes of Fe2+ to Fe3+ ,displacement of halogen,displacement of metals,transfer of elactron..
    u have to revise these 4 example and cuba cari dan selesaikan soalan berkait example in ( refer dalam past year question or any state trial exam )..do as much question you can..
    soalan yg bole dijangka..biasanya soalan yang ditanye..1,observation,2,name of products 3.half equation 4. process (oxidation or reduction)..dan pelbagai..selaluye soalan lebih kurang sama..
    you should memorise some of important oxidising and reducing agent..refer to textbook...
    harap ini boleh membantu anda
