- The reaction between mercurous nitrate and potassium ferricyanide has been studied potentiometrically, using Hg2/Hg22+ electrode. The equivalence point obtained from the maximum ΔE/ΔC corresponds to the formation and precipitation of the compound (Hg2)3[Fe(CN)6]2 both in the case of the direct and the inverse titrations. The titration curves have a regular form: there is a good break in potential at the equivalence paint and the results are accurate and reproducible. The effect of alcohol on the end-point and on the nature of curves has been studied. The results of potentiometric titrations are in conformity with the conclusions of Saxena and Bhargav, obtained by conductance measurements.
