Chromium(II) chloride
Chromium(II) chloride is a chemical compound. Its chemical formula is CrCl2. It is a white crystalline chemical. It dissolves in water to produce a bright blue solution. It is a strong reducing agent. If the water has a little acid in it, hydrogen is produced. If the water has a little base in it, chromium(II) oxide is produced. The water needs to be very pure.
It is made by reacting chromium(III) chloride and hydrogen at a high temperature. It can also be made by reduction of chromium(III) chloride with zinc. It is used in science research.
