Nikkelikarbonaatti

Nikkelikarbonaatti is the common name for nickel(II) carbonate, an inorganic compound with the chemical formula NiCO3. It is a pale green solid that is insoluble in water. Nickel(II) carbonate can be prepared by reacting a soluble nickel salt, such as nickel(II) sulfate, with a soluble carbonate, like sodium carbonate, in an aqueous solution. The reaction results in the precipitation of nickel(II) carbonate.

This compound is primarily used in electroplating processes to deposit a layer of nickel onto other metals. This provides a decorative finish and enhances corrosion resistance. It also finds application in the production of other nickel compounds, such as nickel catalysts used in various chemical reactions. In some specialized ceramic glazes and pigments, nickel(II) carbonate can be employed to impart specific colors.

Nickel(II) carbonate is considered a hazardous substance. It is toxic if swallowed or inhaled and can cause skin and eye irritation. Prolonged or repeated exposure may lead to allergic skin reactions and is suspected of causing cancer. Proper handling procedures, including the use of personal protective equipment, are necessary when working with this chemical. Its disposal should follow local environmental regulations for hazardous waste.
