WebI'm assuming that you're talking about the last reaction—H2SO4 (aq) + 2 NaOH (aq) → Na2SO4 (aq) + 2 H2O (ℓ). When we break this up into its ions, we get H2 (aq) + SO4 (2−) (aq) + 2 Na+ (aq) + 2 OH− (aq) → 2 Na+ = SO4 (2−) (aq) + 2 H2O (ℓ). So we can "cancel" the 2 Na+ (aq) and the SO4 (2−) (aq) on each side. Okay. Web20 nov. 2005 · IO3-: I has an oxidation state of +5. I2: I has an oxidation state of 0. I is moving towards a more negative state, so it is reduced. Therefore, IO3- is the oxidizing agent. I- --> I2 I-: I has an oxidation state of -1 I2: I has an oxidation state of 0 I is moving towards a more positive state, so it is oxidized. Therefore, I- is the reducing ...

Web23 okt. 2014 · In a disproportionation reaction, one reactant should always contain an element that can have at least three oxidation states. 2H 2 O 2 (aq) —> 2H 2 O (l) + O 2 (g) Here the oxidation number in the reactant is (-1), it increases to zero in O 2 and decreases to (-2) in H 2 O. Oxidation number in Hydrogen does not change in the reaction.
