Contents
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.
