Additionally, the chloride ions in the compound can act as a base, allowing them to react with acids.Ĭhromium (II) Chloride Tetrahydrate (II) Chloride Tetrahydrate is not known to have any significant biochemical or physiological effects in humans. This allows it to form complexes with other molecules, such as the chromium (III) complexes mentioned above. Additionally, it can be used to catalyze certain reactions, such as the oxidation of alcohols.Ĭhromium (II) Chloride Tetrahydrate (II) Chloride Tetrahydrate acts as a Lewis acid, meaning that it can accept a pair of electrons. It is also used in the synthesis of other chromium-containing compounds, such as chromium (IV) oxide. It can be used as a reagent in various organic and inorganic syntheses, as well as in the preparation of chromium (III) complexes. Pass hydrogen gas through the solution for 30 minutes to reduce Chromium (III) to Chromium (II)įilter the solution to remove any impuritiesĪdd 4 equivalents of water to the solution to form Chromium (II) Chloride TetrahydrateĪllow the solution to cool and crystallize to obtain the productĬhromium (II) Chloride Tetrahydrate (II) Chloride Tetrahydrate has many applications in scientific research. The synthesis of Chromium (II) Chloride Tetrahydrate can be achieved through a reduction reaction of Chromium (III) Chloride Hexahydrate.Ĭhromium (III) Chloride Hexahydrate, Hydrogen gas, Hydrochloric acid, Waterĭissolve 10 g of Chromium (III) Chloride Hexahydrate in 100 mL of waterĪdd 10 mL of concentrated hydrochloric acid to the solution The reaction is as follows: 2CrCl3 + 4H2O → 2CrCl3♴H2O. The resulting product is then heated to 90-100☌, allowing the tetrahydrate to form. The reaction is as follows: Cr2O3 + 6HCl → 2CrCl3 + 3H2O. This paper will explore the synthesis method, scientific research applications, mechanism of action, biochemical and physiological effects, advantages and limitations for lab experiments, and possible future directions for the use of Chromium (II) Chloride Tetrahydrate.Ĭhromium (II) Chloride Tetrahydrate (II) Chloride Tetrahydrate can be synthesized by combining chromium (III) oxide with hydrochloric acid. Chromium (II) Chloride Tetrahydrate has a variety of uses in scientific research and laboratory experiments, ranging from its use as a reagent to its ability to catalyze certain reactions. It is a pale yellow, crystalline solid that is highly soluble in water. Chromium (II) Chloride Tetrahydrate, also known as Chromium Chloride, is a chemical compound composed of the elements chromium and chlorine.
