MX is a sparingly soluble salt that follows the given solubility equilibrium at 298 K: MX(s) ⇌ M+(aq) + X–(aq); Ksp = 10–10 If the standard reduction potential for M+(aq) + e– → M(s) is E°M+/M = 0.79 V, then the value of the standard reduction potential for the metal/metal insoluble salt electrode E°X–/MX(s)/M is _________ mV. (nearest integer) [Given: 2.303 RTF = 0.059 V]
