Document Summary

4. 1 redox reactions: oxidation is lose electrons, reducing agents donates electrons, reduction is gain electrons, oxidizing agents accepts electrons. Oxidation and reduction always occur together, the # of electrons lost in the oxidation must be equal to the # of electrons gained in the reduction. The rules of how to assign oxidation number, see 4-3: if carbon is bonded to an tom more electronegative it would have a +1 on the oxidation number on the carbon (ex. C-o has +1, c=o has +2: if carbon is bonded to an atom less electronegative it would have a -1 oxidation number on that carbon (ex. C-h has -1: c-c would contribute 0 to the oxidation number of the carbon. Steps of balancing redox reaction, see 4-5: for acidic condition: add the # of h+ ions to the side deficient in h, for basic condition: add the # of h2o molecules to the side deficient in.
