Sulfur with metals

Sulfur acts as an oxidizer for metals. Sulfur with metals very easily connects. Therefore, there are many sulfurous metals in nature. These are the ores from which metals are mined. Sulfur combines directly with almost all metals, releasing heat. It is necessary only in one place to set fire to mixtures of sulfur with metals, and the reactions will continue without heating.

When heated, sulfur interacts with many metals, often - very violently. Sometimes sulfur with metals lights up when ignited. In this interaction, sulphides are formed. For example, copper easily combines with sulfur when heated.

We add hot copper foil to the flask with boiling sulfur. Copper burns in sulfur vapor, it burns to red, releasing heat and light and attaching sulfur atoms to itself:

Cu + S = CuS.

2Na + S = Na2S;

Ca + S = CaS;

2Al + 3S = Al2S3;
