化学的特性
Chromic sulfate, also known as chromium(III) sulfate (Cr₂(SO₄)₃), is a violet or red powder that is insoluble in water and acids. Its basic form, produced by the reduction of sodium dichromate, is used in tanning. Other uses include chrome plating, chromium alloys, mordants, catalysts, green paints and varnishes, green ink, and ceramic glazes. The primary hazard of this material is its potential to cause environmental damage if released. Immediate steps should be taken to limit its spread into the environment.
