A sodium ion-selective electrode increased in voltage by 59.16 mV when the sodium cation concentration was increased by a factor of 10. A S2-ion-selective electrode measured a decrease of 29.58 mV when the sulfide concentration increased by a factor of 10. Why? Select all that apply A. Cations always increase the measured potential by z x 59.16 mV where z is the charge on the cation. UB. Anions always decrease the measured potential by z x 59.16 mV where z is the charge on the anion. C. Cations always increase the measured potential by 59.16 mV/z, where z is the charge on the cation. D. Anions always decrease the measured potential by 59.16 mV/z, where z is the charge on the anion.
