Gran plot for ise
 - Wikipedia)
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 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 $${\displaystyle K_{a}={\frac {[H^{+}]_{i}[A^{-}]_{i}}{[HA]_{i}}}}$$ , we have at any i'th … 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 … 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 … See more For a strong acid-strong base titration monitored by pH, we have at any i'th point in the titration $${\displaystyle K_{w^{}}=[H^{+}]_{i}[OH^{-}]_{i}}$$ where Kw is the water autoprotolysis constant. 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 during an acid-base titration to estimate the adventitious CO2 content in the base solution. This is illustrated in the … See more Potentiometric data are also used to monitor species other than $${\displaystyle H^{+_{}}}$$. When monitoring any species $${\displaystyle S^{1_{}}}$$ by potentiometry, one … See more WebGran's plot titration and flow injection titration of sulfate in ground and drinking water with a barium ion-selective electrode October 1994 Fresenius Journal of Analytical Chemistry 350(10):630-632
