CADMIUM HYDROXIDE Usage And Synthesis

Chemical Properties

White powder

Physical properties

White powder or crystal; trigonal or hexagonal crystal system; density 4.79 g/cm³; decomposes slowly at 130°C; dehydration completes at 300°C; insoluble in water (2.6 mg/L at 20°C); soluble in dilute acids.

Uses

In storage battery electrodes.

Uses

Cadmium hydroxide is used to prepare negative electrodes for cadmium-nickel batteries. It is a useful in biochemical for proteomics research. It may be used in cadmium plating and cadmium salt.

Preparation

Cadmium hydroxide may be precipitated by adding any cadmium salt solution to a boiling solution of caustic soda or caustic potash:
CdCl₂ + 2NaOH → Cd(OH)₂ + 2NaCl.
