Here is a brief description of platinum. The above shows a platinum crucible.
Platinum is a beautiful silvery-white metal, when pure, and is malleable and ductile.
The metal does not oxidise in air. It is corroded by halogens, cyanides, sulphur and alkalis. Hydrogen and oxygen gas mixtures explode in the presence of platinum wire. Here is a brief summary of the isolation of platinum. It would not normally be necessary to make a sample of platinum in the laboratory as the metal is available commercially.
