SHORT DESCRIPTION

Nickel Sulphate [NiSO₄·6H₂O] Extra Pure is a crystalline, green-colored compound of high purity, widely utilized in analytical, electrochemical, and industrial applications. It is primarily used in electroplating processes to deposit a uniform layer of nickel onto metal surfaces, enhancing corrosion resistance and aesthetic appeal. Its consistent composition makes it ideal for high-precision electroforming and battery component manufacturing, especially in nickel-cadmium and nickel-metal hydride batteries.

In laboratories, it serves as a reagent for chemical analysis, particularly in qualitative and quantitative detection of nickel ions. It is also involved in catalyst production, ceramic coloring, and metal surface treatment. The Extra Pure grade guarantees minimal impurities, ensuring reliable performance in sensitive experimental setups. Due to its toxic and irritant nature, it should be handled with appropriate personal protective equipment and stored in a cool, dry place in tightly closed containers.

SAFETY HANDLING PRECAUTIONS

SAFETY PRECAUTIONS

Personal Protective Equipment (PPE):

Wear a lab coat, nitrile gloves, and chemical splash goggles.
Use a dust mask or work under a fume hood to avoid inhalation of dust or mist.

Handling:

Avoid contact with skin, eyes, and clothing.
Do not breathe dust or solution vapors.
Wash hands thoroughly after handling.
Handle with care to prevent spills and dispersion of dust.

Storage:

Store in a tightly sealed container in a cool, dry, and well-ventilated area.
Keep away from incompatible substances such as strong acids and reducing agents.
Avoid exposure to moisture and direct sunlight.

FIRST AID MEASURES

Inhalation:

Remove the person to fresh air immediately.
Seek medical attention if symptoms like coughing or shortness of breath develop.

Skin Contact:

Wash with plenty of soap and water.
Remove and wash contaminated clothing.
Seek medical advice if irritation or rash appears.

Eye Contact:

Rinse cautiously with water for several minutes.
Remove contact lenses if present and easy to do.
Continue rinsing and seek medical attention if irritation persists.

Ingestion:

Rinse your mouth thoroughly with water.
Do not induce vomiting.
Seek immediate medical attention.

FIRE FIGHTING MEASURES

Flammability:

Not flammable; may decompose at high temperatures.

Extinguishing Media:

Use water spray, dry chemical, carbon dioxide (CO₂), or foam.
Cool exposed containers with water spray to prevent pressure buildup.

Hazardous Combustion Products:
