Present name. - Zincic Acetate. Zn2C2H3O2,3H1O.
May be obtained from the operative chemists.
Characters and Tests. - Thin translucent and colourless crystalline plates, of a pearly lustre, with a sharp unpleasant taste; evolving Acetic Acid when decomposed by Sulphuric Acid; soluble in water, and the solution precipitated pure white by Sulphuretted Hydrogen. A dilute watery solution is not affected by Chloride of Barium or Nitrate of Silver; and, when slightly acidulated with Hydrochloric Acid, is not precipitated by Sulphuretted Hydrogen; after it has been boiled for a few minutes with a little Nitric Acid, it yields with Ammonia a white precipitate entirely soluble without colour in an excess of the re-agent.
Preparation. - Solution in distilled water.
