A Gran plot (also known as Gran titration or the Gran method) is a common means of standardizing a titrate or titrant by estimating the equivalence volume or end point in a strong acid-strong base titration or in a potentiometric titration. Such plots have been also used to calibrate glass electrodes, to … See more The Gran plot is based on the Nernst equation which can be written as $${\displaystyle E=E^{0}+s\log\{H^{+}\}}$$ where E is a measured electrode potential, E is a standard electrode potential, s is the slope, ideally equal … See more Martell and Motekaitis (1992) use the most linear regions and exploit the difference in equivalence volumes between acid-side and base-side plots … See more Note that the above analysis requires prior knowledge of $${\displaystyle b_{0^{}}}$$ and $${\displaystyle b_{1^{}}}$$. If a pH electrode is not well calibrated, an offset correction can be computed in situ from the acid-side Gran slope: • For … See more For a strong acid-strong base titration monitored by pH, we have at any i'th point in the titration $${\displaystyle K_{w^{}}=[H^{+}]_{i}[OH^{-}]_{i}}$$ See more The method can be used to estimate the dissociation constants of weak acids, as well as their concentrations (Gran, 1952). With an acid represented by HA, where See more Potentiometric data are also used to monitor species other than $${\displaystyle H^{+_{}}}$$. When monitoring any species $${\displaystyle S^{1_{}}}$$ by potentiometry, one can apply the same formalism with To illustrate, … See more In any titration lacking buffering components, both before-equivalence and beyond-equivalence plots should ideally cross the x axis at the same point. Non-ideal behaviour can result from measurement errors (e.g. a poorly calibrated … See more WebArticle Views are the COUNTER-compliant sum of full text article downloads since November 2008 (both PDF and HTML) across all institutions and individuals. http://zimmer.csufresno.edu/~davidz/Chem102/pHGrans/pHGrans.html how do you know if you have cholestasis
