Al2(SO4)3, aluminum sulfate SO4^- is always -2, and there are three which gives total negative charge of -6, therefore each aluminum must be +3. Bonds between atoms of the same element (homonuclear bonds) are always divided equally. To find the correct oxidation state of Cr in Cr2(SO4)3 (Chromium (III) sulfate), and each element in the molecule, we use a few rules and some simple math. Assign an oxidation number of -2 to oxygen (with exceptions). There are a few exceptions to this rule: When oxygen is in its elemental state (O 2), its oxidation number is 0, as is the case for all elemental atoms. important attention : when you are calculatinn oxidation numbers DO NOT CONSIDER MULTPY NUMBER. Sulphate = SO4 2- so S + -2x4 = -2, S-8=-2, so S=+6. 1 Answer. Different ways of displaying oxidation numbers of ethanol and acetic acid. Trending Questions. b.
