Nickel Acetate Formula – Structure, Properties, Uses, Sample Questions

Nickel (Ni), is a metal having atomic no 28 with the symbol Ni, It is a shiny silvery-white metal with a slight golden sheen. Nickel is one of the transition metals, hard and malleable. Pure nickel, powdered to maximize reaction surface area, shows considerable chemical activity

Carbon (C), is a non-metallic chemical element in group 14 of the periodic table. Although widely distributed in nature, carbon is not abundant enough to make up only about 0.025% of the Earth’s crust but forms more compounds than all other elements combined.

Hydrogen (H), a colorless, odorless, tasteless, flammable gaseous substance, is the simplest member of the chemical element family. A hydrogen atom has a nucleus made up of protons carrying a positive charge of one unit. Electrons are also associated with this nucleus, which carries one unit of negative charge. Under normal conditions, gaseous hydrogen is a loose accumulation of hydrogen molecules, each composed of a pair of atoms,  diatomic H₂ molecules.

Oxygen(O) is a chemical element with the symbol O and atomic number 8. It is a highly reactive nonmetal and oxidizing agent that readily forms oxides with most elements as well as other compounds.

Nickel Acetate is a sparingly soluble compound with the formula Ni(CH₃CO₂)₂ This compound can be obtained by treating nickel carbonate with acetic acid. Nickel acetate crystals were observed to have an octahedral structure with a nickel in the center coordinated by four water molecules and two acetate ligands. It is a green crystalline inorganic compound that releases toxic gases when heated. Nickel acetate is used in textile dyeing processes, electroplating, and as an intermediate catalyst. Exposure to this material can cause severe dermatitis, skin and asthma allergies, and can cause damage to the lungs, kidneys, gastrointestinal tract, and nervous system. Nickel acetate is a known carcinogen and has been linked to an increased risk of lung and nasal cancers.

Structure of Nickel Acetate

Nickel acetate is a  chemical compound that is moderately soluble in water with the chemical formula Ni(CH₃CO₂)₂.

Preparation of Nickel Acetate

Nickel Acetate. can be prepared using various methods some of which are listed below:

• The compound can be prepared by treating nickel or nickel(II) carbonate with acetic acid.

NiCO₃ + 2CH₃CO₂H + 3H₂O → Ni(CH₃CO₂)₂·4H₂O + CO.

• Reaction between nickel nitrate and sodium acetate yields Nickel Acetate.

2NaCH₃COO + Ni(NO₃)  → Ni(CH₃COO)₂↓ + 2NaNO₃

• Reaction between nickel sulfate and calcium acetate yields Nickel Acetate.

Ca(CH₃COO)₂ + NiSO₄  → Ni(CH₃COO)₂ + CaSO₄↓

• Reaction between Nickel chloride and concentrated acetic acid yields Nickel Acetate.

2CH₃COOH + NiCl₂ → Ni(CH₃COO)₂↓ + 2HCl
