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.

The Uses of CADMIUM HYDROXIDE

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.

The Uses of CADMIUM HYDROXIDE

In storage battery electrodes.

What are the applications of Application

Cadmium hydroxide is a useful biochemical for proteomics research

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.
