    Teds of the Mercurom Salts- Tests- '(a)—Caustic Alkalies, as Potash, Lime, and Soda, give a Mack ppt. (Hg^O.) (b) —Iodide of Potassium (Kl) gives a ffreeiip-pt. (c) —Yellow Chromate of Potassium (K^CrO^) gives a 7'ed ppt. Tests—^ lodum (I). 2NaI + 2H,S0, + MnO, = I, + Na-.SO^ + MnSO, + 2H,0 /(rt)—In laminar crystals, with an acrid taste, dark colour, and metallic lustre, wbich, when heated, yield a beautiful violct-colmired vapour.
