Read the following statements carefully.

(i) According to a convention 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) / Zn is – 0.76. This negative value indicates that Zn2+ ion reduces less easily then Hions.

(iii) Copper does not dissolve in HCl but dissolves in HNO3 as in nitric acid it gets oxidised by nitrate ion.
