Determination of blood ph by potentiometry
Webequation, pH = pK a + log(a OAc-/a HOAc). Calculate and report the pH obtained in this way, again being careful to specify how activities were obtained. It is also interesting to … WebCa2+ in serum, plasma, whole blood, and other biological fluids can be measured by direct potentiometry with ion-selective electrodes and a number of reliable instruments are commercially available for this measurement. Several factors affect the Ca2+ concentration and must be carefully controlled for the results to be meaningful.

WebConsequently, additional uncertainty of about ±0.01 pH unit is introduced into pH measurements. Thus, unless extreme care is taken, typical pH measurements have an uncertainty of at least ±0.02 pH unit. Other ion-selective electrodes respond to an analyte ion concentration difference in a way similar to that of the pH electrode.

WebFor 01 most chemists, potentiometry with ion-selective electrodes (ISEs) probably just means pH measurements with a glass electrode. Only those interested in clinical analysis might know that ISEs, routinely used for the determination of blood electrolytes, have a market size comparable to that of glass electrodes.
