COPPER(II) SULFIDE Chemical Properties,Uses,Production

Chemical Properties

Copper(II) sulfide, CuS, [1317-40-4], MW 95.6, occurs in nature as the blue-black mineral covellite, [19138-68-2]. It is insoluble in water but is decomposed by nitric acid. In moist air, it is oxidized to copper(II) sulfate. The rate of oxidation is accelerated in the presence of alkali. Copper(II) sulfide is used as an antifouling pigment and in the preparation of aniline black dyes.

Uses

In antifouling paints; in preparation of mixed catalysts; in development of aniline black dye in textile printing.

Preparation

Copper(II) sulfide is prepared by heating copper(I) sulfide in the presence of excess sulfur in a hydrogen atmosphere. Ethanol solutions of anhydrous copper(II) chloride precipitate the copper(II) sulfide on the addition of hydrogen sulfide.

Definition

ChEBI: A copper sulfide in which the metal is in the +2 oxidation state.

Hazard

Toxic by ingestion.
