Chromic chloride

Chromic chloride or chromium(III) chloride is a chemical compound with the formula CrCl3. It is a high melting white solid used in various industrial applications.

Chemistry

Chromic chloride is a typical example of a transition metal chloride. It is a strong Lewis acid, which means it can accept a pair of electrons to form a covalent bond. It is also a paramagnetic compound, which means it is attracted to magnetic fields.

Preparation

Chromic chloride can be prepared by the reaction of chromium with hydrochloric acid. This reaction produces a green solution of chromium(III) chloride. The green solution can be evaporated to produce a hydrated form of the compound.

Properties

Chromic chloride is a white solid at room temperature. It has a high melting point and is soluble in water. It is a strong oxidizing agent, which means it can gain electrons and cause other substances to lose electrons.

Applications

Chromic chloride is used in various industrial applications. It is used as a catalyst in the production of polyethylene and polypropylene. It is also used in the production of chromium plating and in the dyeing of textiles.

Health effects

Exposure to chromic chloride can cause skin and eye irritation. Ingestion or inhalation can cause nausea, vomiting, and shortness of breath. Long-term exposure can lead to lung damage and cancer.
