“…26 For example, storage of MeHgCl (5610 74 mol litre 71 ) in HCl solution with pH 1 for a week did not change its polarogram. 26,121 As a rule, protolysis of OMC is a lengthy procedure carried out under sufficiently drastic conditions (elevated temperatures, high acid concentrations). 26 For the described 121 systems, the protolytic effect was observed even in weakly acidic media (pH 4 4.8 ± 5.5) at room temperatures; after the solutions of pentafluorophenylmercuric bromide and bis(phenylethynyl)mercury were neutralized with an alkali in the electrochemical cell, the original state was completely recovered, which pointed to the absence of protolysis of these compounds.…”
