    Can anyone explain to me how the oxidation state of the water molecules on the left can be compared with the oxidation state of the hydroxide ion, which is considered as a whole, rather than as two atoms?Name:  IMG_1889.jpg

    This question doesn't really make sense as molecules can't have oxidation states. In both H2O and OH- Oxygen's oxidation state is 2- and Hydrogen's oxidation state is 1+, if that helps.
