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 WebGran (TV series) children's animation from the early 80's.

Webplot. This is commonly used to interpolate to other temperatures.10,11 Extrapolation of experimental data is, of course, not advised. We can understand this by realizing that ∆H can be re-written as: ∆H = ∆G + T∆S (5) Here ∆G is the Gibbs free energy change and ∆S is the entropy change. The linear relation mentioned only holds if ...
