Which of the following facts is not truegtA. if `E^(@) (M^(n+ //M)` is negative, `H^(+)` will be reduced to `H^(2)` by the metal M.B. If `E^(@)(M^(n+)//m)` is positive, `M^(n+)` will be reduced to M by `H_(2)`C. In a cell `M^(n+) // M` electrode is attached to hydrogen-half cell. To produce spontaneous cell reaction, metal M generally acts as negative electrode.D. Compounds of active metals (Zn, Na, Mg) are reducible by `H_(2)` whereas those of noble metals (Cu, Ag, Au) are not reducible. |
