Question: Junction potentials, consider two well-mixed reservoirs of aqueous salt at 25C, as in Fig. 24.4-2, separated by a stagnant region. Salt concentrations are 1.0 N

Junction potentials, consider two well-mixed reservoirs of aqueous salt at 25°C, as in Fig. 24.4-2, separated by a stagnant region. Salt concentrations are 1.0 N on the left (1) and 0.1 N on the right (2). Estimate junction potentials for NaC1 and for KC1 using the ion diffusivities of Problem 24A.3. Assume constant ion activity coefficients. Which compartment will be the more positive? Why?
