Justify that the following reactions are redox reactions : CuO(s)+H_(2)(g)toCu(s)+H_(2)O(g) |

Answer» SOLUTION :`OVERSET(+2-2)(CUO(s))+overset(0)H_(2)(g)tooverset(0)(Cu)(s)+overset(+1-2)(H_(2)O)(g)` In this reaction, the O.S. of Cu is decreasing from +2 (in CuO) to 0 (in Cu) while that of hydrogen is increasing from O ( in `H_(2)` ) to +1 (in `H_(2)O` ). Thus, the reaction involves the REDUCTION of Cuo and OXIDATION of hydrogen. HENCE, it is a redox reaction, |
