Question

Balance the following equation in acidic conditions. Phases are optional.

Cu+NO3- = Cu2+ NO

(redox and Oxidation reactions)

Answer 1

The complete reaction is as follows half reactions for the reaction is as follows CuCu2+ (Oxidai on half - reaction ) NOS-NO (Reduction half-reaction) bal ance the atoms other than oxygen and hydrogen Reduction Oxidai on NO^>NO Ll bal ance the oxygen atoms by adding water on both si des NO;>NO+ 2H2O Balance the hydrogen atoms by adding H on both si des Add electrons on both si des to balance thereaction as follows Combined both the equations as follows: CuCu2+ + 2e (1)x3 and (2)x2, then the equation is as follows 2 NO +8 H +6e2 NO+4 H2O Therefore, the balanced equation is as follows ЗСи +2 N048H+ _ > 3 Cu2+ +2 NO +4 H20
