In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH?(aq), and H+(aq) may be added to complete the mass balance. Which...

When balancing redox reactions using the half-reaction method, several conditions apply. Check all the REQUIRED conditions. When combining half-reactions, you must make sure the total number of electrons in each half cancels out. Oxidizing agents gain electrons. Electrons are reactants in the reduction half-reaction The number of electrons transferred by a reducing agent can be found by counting oxidation numbers. For polyatomic ions, the oxidation number of the central atom is the same as the charge. The total charges of...

In addition to mass balance, oxidation-reduction reactions must be balanced such that the number of electrons lost in the oxidation equals the number of electrons gained in the reduction. This balancing can be done by two methods: the half-reaction method or the oxidation number method. The half-reaction method balances the electrons lost in the oxidation half-reaction with the electrons gained in the reduction half-reaction. In either method H2O(l), OH−(aq), and H+(aq) may be added to complete the mass balance. Which...

(a) Determine if one or both of the following reactions can be classified as a redox (oxidation-reduction) reaction. In the case of a redox reaction, identify the species that loses electrons and the species that gains electrons. (Omit states-of-matter from your answer. Enter NONE in any unused answer blanks.) (i) Pd(NO3)3(aq) + Co(s) → Co(NO3)3(aq) + Pd(s) This is a redox reaction? This is not a redox reaction? What loses electrons? What gains electrons? (ii) NiSO4(aq) + NH4OH(aq) → Ni(OH)2(s) + (NH4)2SO4(aq)...
