So, reduction decreases the oxidation number (valency). oxidation number before and after the reaction has taken place. we know there is sulphuric acid (H2SO4) hydrogen ions each have a +1 charge so since there are 2. Zn has an oxidation number (valency) of 0, and is oxidised to Zn2+, an oxidation number of 2+, So oxidation increases the oxidation number (valency). There are three oxygens in this problem, so the total is -6. is CuSO4 + Zn ---> ZnSO4 + Cu a redox reaction? There are 2 sulphur atoms, so S = +7. The oxidation number of a monatomic ion equals the charge of the ion. so,the oxidation number of carbon is 4+ Chemistry copper(II) sulphate. $\ce{VO^{2+} + H_2O \rightarrow VO_2^{+} + 2H^{+} + e^{-}}$ Each time the vanadium is oxidized (and loses another electron), its oxidation state increases by 1. oxidation number S = +6. The Cu has a decrease oxidation number of +2 going to 0 therefore is being reduced the Zn has an increase in oxidation number going from 0 to +2.
