Определение
ChEBI: A compound of chromium and sulfate in which the ratio of chromium (in the +3 oxidation state) to sulfate is 2:3
Общее описание
Dark green to violet crystalline material. Used in paints and inks, ceramics, and in textile dyeing. I Chromic sulfate is noncombustible. The primary hazard of Chromic sulfate is the potential for environmental damage if released. Immediate steps should be taken to limit its spread to the environment.
Реакции воздуха и воды
Water soluble.
Профиль реактивности
Chromic sulfate has weak oxidizing or reducing powers. Redox reactions can however still occur. The majority of compounds in this class are slightly soluble or insoluble in water. If soluble in water, then the solutions are usually neither strongly acidic nor strongly basic. These compounds are not water-reactive.
