NICKEL ACETATE

1. PRODUCT IDENTIFICATION AND CHEMICAL IDENTITY

CHEMICAL STRUCTURE AND DESCRIPTION:

Nickel Acetate (Ni(CH₃COO)₂·4H₂O) is the acetate salt of nickel in the +2 oxidation state. It consists of a nickel ion (Ni²⁺) and two acetate ligands (CH₃COO⁻). It is soluble in water and appears as greenish crystals. It is widely used in electroplating solutions, catalyst production, ceramic and pigment industry, and as a laboratory reagent.

Structural Features:

• Nickel ion in +2 oxidation state

• Two acetate ligands

• Tetrahydrate form (4 water molecules)

• Soluble in water

• Green color (characteristic of Ni²⁺)

13. SUMMARY AND CRITICAL WARNINGS

SUMMARY:

Nickel Acetate (Ni(CH₃COO)₂·4H₂O, CAS 373-02-4) is a greenish crystalline solid or powder with a molecular weight of 248.84 g/mol and density of approximately 1.74 g/cm³. It is soluble in water and has a slight acetic acid odor.

Its most important applications include use in electroplating solutions, catalyst production, ceramic and pigment industry, and as a laboratory reagent.

Nickel compounds may cause allergic reactions and long-term cancer risk. Harmful if swallowed or inhaled. Causes skin irritation, allergic skin reactions, and respiratory tract irritation. Very toxic to aquatic life. Storage should be in cool, dry, well-ventilated areas, in tightly closed containers, away from strong oxidizers and acids.

Key Properties:

CRITICAL WARNINGS:

1. Carcinogenicity: Nickel compounds are classified as Category 1B carcinogens (H351).

2. Allergic Reactions: Skin contact may cause allergic reactions (H317). Inhalation may cause allergy or asthma symptoms (H334).

3. Reproductive Toxicity: May damage fertility or unborn child (H360).

4. Organ Damage: Prolonged exposure causes organ damage (H372).

5. Environmental: Very toxic to aquatic life with long-lasting effects (H410). Must be prevented from entering water and soil sources.

6. Hygroscopic: Slightly hygroscopic; protect from moisture. Store in tightly closed containers.

7. Waste Management: Nickel-containing waste must be processed at specialized disposal facilities.
