ION SELECTIVE ELECTRODES - SlideServe

Creager and colleagues designed a salicylate ion-selective electrode using a PVC membrane impregnated with tetraalkylammonium salicylate. ^20 To determine the ion-selective electrode's selectivity coefficient for benzoate, they prepared a set of salicylate calibration standards in which the concentration of benzoate was held constant at 0.10 M. Using the following data, determine the value of the selectivity coefficient. [salicylate] (M) potential (mV) 1.0 20.2 1.0 ×10^-1 73.5 1.

SOLVED:Calibration curve and propagation of uncertain for exponents. The following data were obtained when a Ca^2 ion-selective electrode was immersed in standard solutions whose ionic strength was constant at 2.0 M. (a) Prepare a calibration curve and find the least-squares slope and intercept and their standard deviations. (b) Calculate the value of βin Equation 14-13. (c) For a measured potential, the calibration curve gives us log[Ca^2 ]. We can compute [Ca^2 ]=10^log[Ca^2 ]. Using rules for
