An ion selective electrode is utilised to determine the concentration of Ca2+ in the presence of Mg2+. The selectivity coefficient for the electrode kij is 0.015. If the concentrations of Ca2+ and Mg2+ are 50 and 500 ppm, respectively, calculate the change in potential (in mV) when the temperature of the measurement cell is increased from 20oC to 40oC.

Question

An ion selective electrode is utilised to determine the concentration of Ca²⁺ in the presence of Mg²⁺. The selectivity coefficient for the electrode k_ij is 0.015. If the concentrations of Ca²⁺ and Mg²⁺ are 50 and 500 ppm, respectively, calculate the change in potential (in mV) when the temperature of the measurement cell is increased from 20^oC to 40^oC.
