The potentials were converted to [Ag+] values for plotting. Note that the filled circles indicate the data points included in the least-squares computations to give the fitted dashed lines.

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 estimate the carbonate content of aqueous solutions, and to estimate the K_a values (acid dissociation constants) of weak acids and bases from titration data.
