Question

Which statement is correct.

Options

A.In SHE, the pressure of dihydrogen gas should be low and pH of solution should be zero.
B.In the reaction H2O2 + O3 → 2H2O + 2O2, H2O2 is oxidised to H2O.
C.The absolute value of electrode potential cannot be determined.
D.According to IUPAC conventions, the standard electrode potential pertains to oxidation reactions only.

Solution

Only anode or cathode can′t work alone so absolute value of reduction potential can′t be determined.
