What is a Nickel sulfate (NiSO₄)?

Nickel sulfate (NiSO₄) is an inorganic compound composed of nickel and sulfate ions. It appears as colorless or greenish crystals and is highly soluble in water. Nickel sulfate is primarily used in electroplating and metal surface treatment, as well as in the production of alloys containing nickel. Industrially, it plays a crucial role in electroplating and battery manufacturing. Nickel-containing electroplating provides corrosion resistance to metal surfaces, which is commonly used in mechanical parts and electrical equipment. It is also related to battery technologies such as nickel-metal hydride (NiMH) batteries and lithium-ion batteries, and is used in their production.

Nickel sulfate is also utilized as a catalyst and in chemical synthesis reactions. However, due to its toxicity, caution is required when handling and disposing of this chemical. Ingestion or skin contact can have harmful effects on health, so proper safety measures must be followed when working with it.
