Volumetric Determination of Mercury and Use of Mercury Salts as Primary Acidimetric Standards

“…The interference by chloride is much less than that by bromide or iodide, and with a little practice fairly accurate values can be obtained by utilizing the normal procedure, particularly if a mixed indicator-phenolphthalein (3 parts) and 1-naphtholphthalein (1 part)-is used as recommended by Das. INTERACTION BETWEEN AMIDE AND MERCURY That mereury(II) oxide is not precipitated in the presence of a variety of substances including amides is well known and is referred to by Mellor (9) and Sidgwick (11). According to Schoeller and Schrauth (10), mercury(II) oxide dissolves in a solution of an amide such as acetamide to give (CH3CO NH)3 Hg; imides, especially cyclic imides such as succinimide, react very easily. Ley and others (6-8) have shown that the complex is only slightly ionized and reacts only slowly with potassium iodide.…”
