This compound is used in a variety of chemical processes and industrial applications, including electroplating, catalyst preparation, and pigment production.

Chemical Structure and Properties

Buy Nickel Carbonate, basic hydrate, is a green crystalline substance. The general formula for this compound is NiCO₃·xH₂O, where x can vary depending on the specific form of the hydrate. The basic nature of the compound is due to the presence of Ni(OH)₂ groups within the structure.

• Appearance: Green crystalline solid (often in the form of a fine powder).

• Solubility: Insoluble in water, but can react with acids to form soluble nickel salts like nickel sulfate or nickel chloride.

• Basicity: Due to the presence of hydroxide groups, nickel carbonate, basic hydrate exhibits a basic character.

• Molecular Weight: Varies based on the number of water molecules (x) in the hydrate, but it is typically around 118.7 g/mol for the basic form with one water molecule.

Synthesis of Nickel Carbonate, Basic Hydrate

Nickel carbonate, basic hydrate can be synthesized through the following methods:

1. Reaction of Nickel Salts with Sodium Carbonate: Nickel carbonate, basic hydrate is typically prepared by reacting a nickel salt, such as nickel sulfate (NiSO₄) or nickel chloride (NiCl₂), with sodium carbonate (Na₂CO₃) in an aqueous solution. The reaction proceeds as follows:

   NiSO4+Na2CO3+H2O→NiCO3⋅xH2O+Na2SO4NiSO₄ + Na₂CO₃ + H₂O → NiCO₃·xH₂O + Na₂SO₄NiSO4​+Na2​CO3​+H2​O→NiCO3​⋅xH2​O+Na2​SO4​

   In this reaction, the sodium carbonate reacts with the nickel salt, forming nickel carbonate, basic hydrate as a precipitate, along with the formation of sodium sulfate (Na₂SO₄).

2. Reaction of Nickel Hydroxide with Carbon Dioxide: Another common method involves reacting nickel hydroxide (Ni(OH)₂) with carbon dioxide (CO₂) in water. This reaction leads to the formation of nickel carbonate, basic hydrate:

   Ni(OH)2+CO2→NiCO3⋅xH2ONi(OH)₂ + CO₂ → NiCO₃·xH₂ONi(OH)2​+CO2​→NiCO3​⋅xH2​O

   The nickel hydroxide is typically prepared by reacting nickel salts with alkali, and then exposing the resulting nickel hydroxide to carbon dioxide to form the carbonate.Buy Nickel Carbonate

Applications of Nickel Carbonate, Basic Hydrate
