oxidation-reduction reactions, 3) calculations in electrochemistry and other areas of chemistry. Rule 0 The following rules are in the form of a hierarchy; that is, the first stated rule takes precedence over subsequent rules if a conflict arises. Rule 1 The oxidation numbers for all the atoms in a neutral molecule must add up to 0.

C. both oxidation and reduction D. neither oxidation nor reduction 23. In the reaction AgNO3(aq)+NaCl(aq) !NaNO3(aq)+AgCl(s), the reactants A. gain electrons, only
Oxidation and Reduction Practice - Solutions In each of the following equations, indicate the element that has been oxidized and the one that has been reduced. You should also label the oxidation state of each before and after the process: 1) 2 Na + FeCl2 Æ 2 NaCl + Fe • Sodium is oxidized, going from a 0 to +1 oxidation state.
Balancing REDOX Reactions: Learn and Practice Reduction-Oxidation reactions (or REDOX reactions) occur when the chemical species involved in the reactions gain and lose electrons. Oxidation and reduction occur simultaneously in order to conserve charge. We can “see” these changes if we assign oxidation numbers to the reactants and products.
