The positive value of the standard electrode potential of Cu2+ / Cu indicates that-
(a) | This redox couple is a stronger reducing agent than the H+ /H2 couple |
(b) | This redox couple is a stronger oxidising agent than H+ /H2 |
(c) | Cu can displace H2 from acid. |
(d) | Cu cannot displace H2 from acid. |
1. (a, b)
