A S2- ion-selective electrode gave an electrodepotential of E = -0.254 V when immersed in a 7.76 10-2 M standard K2S solution. Assuming thatthe electrode behaved ideally, calculate the molarity of an unknownS2- solution which gave a potential of E = -0.228 V?[Hint: An ideal electrode means that the slope of the E vs log[S2-] = 0.05916/zi V, where zi isthe ion charge including sign.]
