Question

The standard reduction-potential for the half-cell

NO^-₃(aq) + 2H⁺ + e^- → NO₂(g) + H₂O is 0.78V

(i) Calculate the reduction-potential in 8MH⁺. 

(ii) What will be the reduction-potential of the half-cell in a neutral solution? Assume all the other species to be at unit concentration.

Answer 1
