CAS nr: 7791-20-0
Molar Mass: 237.69

Description:
Nickel (II) chloride, also known as nickel dichloride, is an inorganic compound with the chemical formula NiCl₂. It is a yellow-green, hygroscopic crystalline solid that is soluble in water and ethanol. The compound exists in two main forms: an anhydrous form (NiCl₂) and a hexahydrate (NiCl₂·6H₂O). The anhydrous form is typically used in industrial applications, while the hydrated form is often found in laboratory settings.

Nickel (II) chloride is primarily used as a precursor in the production of nickel metal, which is important in various applications, including electroplating, the production of batteries, and as a catalyst in chemical processes. Additionally, it plays a key role in the production of other nickel compounds and in the synthesis of pharmaceuticals, fertilizers, and dyes. Nickel chloride is also used in the preparation of nickel-containing catalysts for hydrogenation reactions and as a reagent in analytical chemistry.

Safety and Handling:

Nickel (II) chloride is a hazardous substance, and appropriate safety measures should be taken when handling it. The compound is toxic and poses several health risks, particularly through inhalation or skin contact. Prolonged exposure or high concentrations can lead to nickel toxicity, which can cause skin irritation, respiratory issues, and other health complications.

Hazardous Effects:

• Toxicity: Nickel chloride is classified as harmful if swallowed, inhaled, or absorbed through the skin.
• Carcinogenicity: Nickel compounds, including nickel chloride, have been identified as potential carcinogens, particularly in occupational settings where there is prolonged exposure.
• Corrosive: The substance can be corrosive to skin, eyes, and respiratory tract, leading to irritation or damage upon direct contact.

Precautions:

• Personal Protective Equipment (PPE): It is essential to wear gloves, protective clothing, and eye protection when handling nickel chloride. Additionally, working in well-ventilated areas or using a fume hood is recommended to minimize inhalation risks.
• Storage: Nickel chloride should be stored in tightly sealed containers in a cool, dry place, away from incompatible materials like strong acids or oxidizing agents.
• Disposal: Waste material containing nickel chloride must be disposed of according to local environmental regulations due to its toxicity and potential environmental impact.
