WebEmpress Michiko leaves the Geku, outer shrine at Ise Shrine on April 18, 2024 in Ise, Mie, Japan. The emperor will abdicate at the end of this month. Emperor Akihito and Empress … 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

http://zimmer.csufresno.edu/~davidz/Chem102/GransPlot/GransPlot.html WebAt the time when Gran developed this method, semi-log papers should be used for calculations but those papers were not readily available. This difficulty decreased the use of Gran Plot. By the development of calculator, later on computer and using ion selective electrode, use of Gran Plot is now increasing. breakdown chemically
