Question

Which of the following is correct if
Ex+/x >E°y+/y > Eºz+z?
(1) Z acts as stronger reducing agent
(2) Z® acts as stronger reducing agent
(3) XⓇ acts as stronger oxidizing agent
(4) Both (1) & (3)

Answer 1

Answer:

(4)

Explanation

Greater E° means stronger Oxidizing agent.

Lower E° means stronger Reducing agent.

(Refer: Electrode potential Table in NCERT, Redox Reactions OR Electrochemistry )

E° of x+/x couple is maximum, Hence it will act as a stronger Oxidizing agent i.e. undergo reduction from (x+ to x) state.

So x+ acts as Stronger oxidizing agent.

E° of z+/z couple is minimum, Hence it will act as stronger reducing agent  i.e undergo oxidation from (z to z+) state.

Hence Both (1) & (3).
