Read the following statements carefully.
(i) According to a convention, the cell potential of hydrogen electrode (S.H.E.) is considered to be zero at all temperatures.
(ii) e.m.f. of the cell Pt(s)/H2(g, 1 bar )/H+ (aq, 1 M) || Zn2+ (aq,1M) / Z n is – 0.76. This negative value indicates that Zn2+ ion reduces less easily then H+ ions.
(iii) Copper does not dissolve in HCl but dissolves in HNO3 as in nitric acid it gets oxidised by nitrate ions.
(iv) Inert metals like Pt or Au are used in certain electrodes i.e., these metals does not participate in reaction but provide surface for oxidation and reduction reactions. (v) Fluorine has the highest electrode potential thereby making it the strongest oxidising agent whereas lithium with lowest electrode potential is the weakest oxidising and strongest reducing agent.
Which of the following are the correct statements above?
  • a)
    (iv) and (v)
  • b)
    (i), (ii) and (iv)
  • c)
    (iii), (iv) and (v)
  • d)
    All are correct
Correct answer is option 'D'. Can you explain this answer?

Read the following statements carefully.(i) According to a convention...
Explanation:

Statement (i):
- This statement is correct as per the convention in electrochemistry where the standard hydrogen electrode (S.H.E.) is considered to have a cell potential of zero at all temperatures.

Statement (ii):
- This statement is correct. The negative value of -0.76 for the cell Pt(s)/H2(g, 1 bar )/H+ (aq, 1 M) || Zn2+ (aq,1M) / Zn indicates that Zn2+ ions reduce less easily than H+ ions.

Statement (iii):
- This statement is correct. Copper does not dissolve in HCl but dissolves in HNO3 because in nitric acid, copper gets oxidized by nitrate ions.

Statement (iv):
- This statement is correct. Inert metals like Pt or Au are used in certain electrodes to provide a surface for oxidation and reduction reactions without participating in the reactions themselves.

Statement (v):
- This statement is correct. Fluorine has the highest electrode potential, making it the strongest oxidizing agent, while lithium has the lowest electrode potential, making it the weakest oxidizing and strongest reducing agent.
Therefore, all the given statements (i), (ii), (iii), (iv), and (v) are correct.
