Description

Copper(II) hydroxide, Cu(OH)2, is thermodynamically unstable with respect to decomposition to the oxide. Copper(II) hydroxide prepared by the addition of sodium hydroxide to a salt of copper decomposes at temperatures above 100°C, and in the presence of excess alkali, it decomposes at temperatures above 50°C. It is virtually insoluble in water and decomposes in hot water to the more stable copper(II) oxide and water. Copper(II) hydroxide dissolves quickly in mineral acids and ammonia solution.

Copper hydroxide is an organic molecular entity.

Copper hydroxide Use and Manufacturing

Methods of Manufacturing

The copper salt method neutralizes soluble copper salts, such as copper sulfate solution, with sodium hydroxide solution, and crystallizes and separates the finished copper hydroxide product. Its CuSO4+2NaOH→Cu(OH)2+Na2SO4

Uses

In manufacture of rayon, battery electrodes, other Cu salts; as mordant in dyeing; as pigment; in fungicides, insecticides; as feed additive; in treating and staining paper; in preparation of Schweitzer's reagent; in catalysts.
