Question

The positive value of the standard electrode potential of
(a) this redox couple is a stronger reducing agent than the
2+/Cu indicates that:
Cu
HH2 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
b,d
bc
and
a,c​

Answer 1

Answer:

hope it helps

Explanation:

Positive value for Cu  

2+

/Cu indicates that this reduction takes place easily compared to H  

+

/H  

2

​  

. Hence, it is stronger oxidizing agent, i.e., (b) is correct. It also implies that Cu cannot reduce H  

+

 ions of an acid to H
