Product Description

Raw Material Cobalt chloride with CAS No. 7646-79-9

Product Overview

Cobaltous chloride, chemical formula CoCl2. It is pink to red crystal, and its anhydrate is blue. It has slight deliquescent, soluble in water, ethanol, ether, acetone and glycerin. It is used as an analytical reagent, an indicator for humidity and moisture, and ammonia absorbent. Its melting point is 86°C, The cobalt chloride crystal is stable at room temperature, it will lose crystal water to blue when heated, and turns red again in humid air. It will turn blue if heat aqueous solution or add concentrated hydrochloric acid, chloride or organic solvent into it. It will crystallize at 30 to 45 ° C, and start weathering and turbidization, it will become tetrahydrate after heated at 45 to 50 ° C for 4 h, and become anhydrate after heated to 110 ° C. It has weak toxicity. It should be noted that cobalt is not radioactive, only medical cobalt-60 is radioactive, so you can use this product safely.
