I. It is assigned a zero potential at all temperature corresponding to the reaction.
II. Platinum electrode coated with platinum black is dipped in acidic solution and H2 gas is bubbled through it.
III. Concentration of both are oxidised and reduced forms of hydrogen is maintained at unity.
 Select the correct facts
  • a)
    I , II ,III
  • b)
    II ,III
  • c)
    I ,II
  • d)
    I ,III
Correct answer is option 'A'. Can you explain this answer?
Verified Answer
Consider some facts about Standard Hydrogen Electrode(SHE).I. It is as...

It is oxidation half-cell

H2 (reduced part) is at 1 bar. H+ (oxidised part) is at 1 M. 

It is reduction half-cell

In this case also, oxidised and reduced parts are at unity.

Then (I), (II) and (III) are correct facts.
