Identify which reactants are being oxidized (the oxidation number increases when it reacts) and which are being reduced (the oxidation number goes down). b. pH = 11.05, What are the coefficients when the chemical equation below is balanced? ... l PbO2(s), PbSO4(s) l Pb (s) where the comma between PbO2 (s) and PbSO4 (s) denotes a heterogeneous mixture . B. H+. B. increases by 4. Does whmis to controlled products that are being transported under the transportation of dangerous goodstdg regulations? SO42- → S ... 2. Step 2: Write the skeletons of the oxidation and reduction half-reactions. Different ways of displaying oxidation numbers of ethanol and acetic acid. The material on this site can not be reproduced, distributed, transmitted, cached or otherwise used, except with prior written permission of Multiply. (The skeleton reactions contain the formulas of the compounds oxidized and reduced, but the atoms and electrons have not yet been balanced.) …, lence electrons in shell 1 b.NaOH(aq) + H2SO4(aq) = H2O(l) + Na(SO4)2(aq) Answer to Oxidation Numbers 1. The alkali metals (group I) always have an oxidation number of +1. There are three oxygens in this problem, so the total is -6.
