Cadmium nitrate is the cadmium salt of nitric acid, with the formula Cd(NO3)2. It is commonly encountered as hydrate.

Properties

Chemical

Heating cadmium nitrate causes it to decompose to cadmium oxide, and nitrogen dioxide.

Physical

Cadmium nitrate is a crystalline solid, soluble in water.

Availability

Cadmium nitrate is sold by chemical suppliers, but it's not easy to acquire, due to its hazards.

Preparation

Can be prepared by dissolving cadmium metal or better, cadmium oxide in nitric acid.

Projects

  • Flash powder
  • Make CdS nanoparticles[1]

Handling

Safety

Cadmium nitrate is extremely toxic and is classified as Group 1 carcinogen. Wear proper protection when handling it.

Storage

Cadmium nitrate should be kept in closed and air-tight bottles, as it's hygroscopic.

Disposal

Should be converted to an insoluble cadmium compound, such as cadmium sulfide and taken to hazardous waste disposal centers.
