Resumen
Methylmercury solutions in chloroform (1000 mgHg/L) were titrated potentiometrically, using saturated calomel and silver electrodes, and potassium iodide aqueous solution (5 mmols/L) as the titrant. For comparison, mercuric ion and methylmercury aqueous solutions were also titrated, under the same conditions. The proposed procedure showed that the standardization of organomercurial solutions is possible, with great exactness, avoiding any oxidative pre-treatment.
