At 25°C, a cell filled with 0.01 demal KCI solution gave a resistance of 484.02. The following data for NaCl solutions were then taken in the same cell at 25°C: Normality 0.0005 0.0010 0.0020 0.0050 Resistance ( SI) 10910 5494 2772 1129 Evaluate the equivalent conductance (in cm² 2-¹ mol-¹) of NaCl at the limit of infinite dilution. The specific conductance of a 0.01 demal KCI solution is 0.00140877 $2¹cm-¹. Express your answer in four significant figures.

The potassium ion selective electrode uses valinomycin as its ionophore to achieve high level of selectivity over other ions. Given the following selectivity data (kij) for this ISE, answer the following questions: (You may assume that activity = concentration). Interferant ion Na+ Ca²+ Mg2+ Log kij -4 -7 -7 a) How much greater must [Na+] be than [K+] for the two ions to give an equal response? (c) If the calibration constant (Econst) was previously found to be 0.197 V. Calculate [K+] if the ISE gives a reading of -0.029 V in a solution which also contains 0.5 M Nat and 0.2 M Ca²+. Give the answer in μM (micro moles per litre).
