Cobalt sulfate (CoSO4) heptahydrate

Description:
Cobalt sulfate heptahydrate (CoSO4·7H2O) is an inorganic compound characterized by its bright pink color, which is attributed to the presence of cobalt ions. It is a crystalline solid that is highly soluble in water, forming a solution that can exhibit a slightly acidic pH. This compound is commonly used in various applications, including as a precursor in the production of cobalt-based catalysts, in electroplating, and as a source of cobalt in fertilizers. Cobalt sulfate heptahydrate is also utilized in the preparation of cobalt salts and in the dyeing of textiles. In terms of safety, it is important to handle this substance with care, as cobalt compounds can be toxic and may cause skin and respiratory irritation. Proper protective equipment should be used when working with it. The heptahydrate form indicates that it contains seven molecules of water for each formula unit of cobalt sulfate, which plays a significant role in its physical properties and solubility.
