The more positive the value of , the greater is the tendency of the species to get reduced. Using the standard electrode potential of redox couples given below find out which of the following is the strongest oxidising agent. values: ;
1
2
3
4
Explanation:
Since has highest positive value of , therefore, is the strongest oxidising agent with highest tendency to get reduced.

(I) (II) Role of hydrogen peroxide in the above reactions is, respectively
1 Oxidizing agent in (I) and reducing agent in (II)
2 Reducing agent in (I) and oxidizing agent in (II)
3 Reducing agent in (I) and (II)
4 Oxidizing agent in (I) and (II)
Explanation:
reduces to in (I) and to Ag in (II) So, is acts as reducing agent in both reactions.

Statement A : A negative value of means that the redox couple is weaker reducing agent than the couple. Statement B : A negative means that the redox couple is stronger reducing agent than the .
1 Statement A is correct but Statement B is incorrect.
2 Statement A is incorrect but Statement B is correct.
3 Both statements are correct.
4 Both Statements are incorrect.
Explanation:
As we know couple has zero standard reduction potential so, ions having positive value are weaker reducing agent, while ions having negative value are stronger reducing agent.
