Supersaturated monomolecular solutions of Hg(OH) 2 up to a concentration of 10 −2 M can be obtained by adding Cu(NO 3 ) 2 to a solution of the mercury complex of EDTA, introducing two NaOH and running the mixture through an anion exchanger. Solutions so obtained have been titrated with HNO 3 in order to obtain the protonation curve of Hg(OH) 2 . Measurements were carried out at 13° C, 20° C, 30° C, 40° C and with solution containing various amounts of NaNO 3 . The results extrapolated to zero ionic strength are:.
