![i{a)—Thin translucent, crystalline plates, having a sharp, unpleasant taste. Soluble in water. (&)—A dilute, watery solution is nut affected by Chloride of Barium (Bad.,), (absence of Sulphates), or Nitrate of Silver (AgNOj), (absence of Chlorides) ; and when slightly' _, / acidulated with Hvdrochloric Acid (HCl) lESTS—< jg ^^^^^ pp^^j_ Sulphuretted Hydrogen (HjS), (absence of Arsenic, Copper, &c). (c)—After it has been boiled for a few minutes, with a little Nitric Acid (HNO3), it yields with Ammonia (NH^HO) a wJiitr 'ppt. entirely soluble, without colour, in excess of the \ reagent (absence of Iron).
