Cadmium chloride

Cadmium chloride is an inorganic salt composed of cadmium and chloride ions, with the formula CdCl₂. It is a colorless, water-soluble solid used in chemical synthesis, electroplating, and laboratory research.

Cadmium: Cadmium is a soft, bluish-white metal with atomic number 48 and substantial toxicity. Cadmium chloride supplies cadmium ions, whose chemistry and hazards shape the salt’s uses.
Electroplating: Electroplating deposits a thin metal coating on a surface by using electric current in an electrolyte. Cadmium chloride has served as an electrolyte component in cadmium-plating processes.
Solubility: Solubility is the maximum amount of a substance that can dissolve in a specified solvent under defined conditions. Cadmium chloride dissolves readily in water, enabling solution-based handling and reactions.
Carcinogen: A carcinogen is an agent capable of causing cancer in humans or other organisms. Cadmium compounds, including cadmium chloride, are treated as carcinogenic hazards.
Cadmium nitrate: Cadmium nitrate is a water-soluble cadmium salt containing nitrate ions, commonly encountered as a hydrate. It provides cadmium ions like CdCl₂ but has different anions and reaction behavior.
Chloride: Chloride is the negatively charged ion Cl⁻, formed when chlorine gains an electron. Two chloride ions balance each cadmium ion in the compound’s formula.
Cadmium plating: Cadmium plating is the electrodeposition of a cadmium coating, used for corrosion protection and electrical contacts. This is a specific metal-finishing use associated with cadmium chloride solutions.
Hydration: Hydration is the association of water molecules with dissolved ions or incorporation of water into a solid structure. Water coordination helps explain hydrated forms and the salt’s behavior in aqueous solution.
Occupational exposure limit: An occupational exposure limit is a regulatory or advisory concentration threshold for hazardous substances in workplace air. Workplace limits govern permissible airborne exposure to cadmium compounds.
Cadmium sulfate: Cadmium sulfate is an inorganic cadmium salt with formula CdSO₄, often encountered as a hydrate. Its sulfate counterion changes solubility and reactivity compared with cadmium chloride.
