Question

solve this plz ii)... ​

Answer 1

Answer:

(I)Manganese[exhibit 5 oxidation states]

(ii) Copper is stronger oxidising agent than 2H^(+1)/H2 (whose E° is 0V), and thus, value of E° for copper is positive.

Explanation:

(ii) Cu^(2+)+ H2 gives Cu+ 2H^(+1)

For this reaction to be feasible, E°cell should be positive.

E°cell=E°[Cu^(2+)/Cu]+E°[H2/2H^(+1)]

E° for H2 is zero.

So E°[Cu^(2+)/Cu] must be positive.
