What is a Cobalt(II) sulfate (CoSO₄)?

Cobalt(II) sulfate (CoSO₄) is an inorganic compound composed of cobalt and sulfate ions. It typically appears as a pale red crystalline solid or powder and is soluble in water. Industrially, it is widely used as a cobalt compound in various applications. Cobalt(II) sulfate plays a key role in the manufacturing of cobalt-containing chemical products, particularly in electroplating and the production of batteries, such as lithium-ion batteries and nickel-cadmium batteries. Cobalt is an important metal for improving battery performance.

In addition, cobalt sulfate is used in chemical analysis and as a catalyst in some processes. In the agricultural sector, cobalt is an essential trace element for plant growth, and therefore, cobalt sulfate is sometimes used in fertilizers. However, cobalt compounds are toxic, and proper handling and storage are necessary.
