WebSep 1, 2006 · The preferred chemical state for mercury in a geologic repository would be the sulphide HgS, which is a sparingly soluble and stable crystalline solid and the dominating mercury mineral (cinnabar) in nature. Mercury in waste would be present as soluble compounds, as well as the oxide and elemental and possibly also as the sulphide. WebHgS is insoluble in HNO3. 3MS + 8HNO3 → 3M (NO3)2 + 2NO + 3S + 4H2O (M = Cu, Cd or Pb) Bi2S3 + 8HNO3 → 2Bi (NO3)2 + 2NO + 3S + 4H2O (a) Test for Hg2+: HgS dissolves in aqua-regia to form HgCl2. 3HgS + 2HNO3 + 6HCl → 3HgCl2 + 2NO + 3S + 4H2O (i) Reaction with SnCl2 gives white ppt. of Hg2Cl2, which decomposes to grey Hg.

Web- It is composed of two substances - It is uniform throughout Which of the following substances are soluble in water? - Methanol - Vitamin A - Hexane - KCl - Methanol - KCl Classify each substance as a nonelectrolyte, weak electrolyte, or strong electrolyte. NaOH: - Nonelectrolyte - Weak electrolyte - Strong electrolyte Strong electrolyte WebAnother way of answering why HgS does not dissolve is to say that it has a very low solubility product (if you understand what that is). Hg (OH)2 is a weak base and it reacts with acids. For example, with HCl, it gives the salt mercuric chloride, which dissolves in water. Hg (OH)2 + 2 HCl —→ HgCl2 + 2 H2O. bakenjoin https://acebodyworx2020.com
