Nickel Chloride and Nickel Sulfate are both used in the electroplating industry. They are essential components of nickel electroplating baths, which are used to deposit a layer of nickel onto metal surfaces. These chemicals help enhance corrosion resistance, improve the appearance, and provide a protective coating on various objects. Nickel Chloride is a greenish crystalline solid, while Nickel Sulfate appears as a pale green or blue crystal.
