Question

Which statement does NOT correctly describe a standard hydrogen electrode (SHE)? The SHE is assigned a standard reduction potential of exactly 1 V. 2 H^+ (aq) + 2 e H_2(g) pt|H_2 (G, 1 atm)|H^+ (aq, 1 M)|| ||H^+(aq, 1M)|H_2(g, 1 atm)| Pt The SHE consists of a platinum electrode immersed in an acid solution and a stream of hydrogen gas. A concentration cell is constructed by using the same half - reaction for both the cathode and anode. What is E^0 for a concentration cell that combines silver electrodes in contact With 0.10 M silver nitrate and 0.00003 M silver nitrate solutions? (E^0 = +0.80 V for Ag/Ag^+) a. +0.21 V d. 0.21 V B. +0.59 V E.+1.01 V C. +0.80 V

Explanation / Answer

A:- a. SHE is assigned a standard reduction potential of exactly 1 V => is not correctly described, because SHE assigned a standard reduction potential of exactly 0.0 V
