Data below come from the graph in Box 14-2, for which the separate solutions method was used

Question:

Data below come from the graph in Box 14-2, for which the separate solutions method was used to measure selectivity coefficients for a sodium ion-selective electrode at 21.5°C. Use Equation 14-11 to calculate log K^Pot for each line below.

(EMg+ - ENa) at A= 103 = -0.385 V = log Kot. „Mg 2+ = ? Na
