In this experiment students study the behavior of copper in sulfur vapor, a piece of sulfur is heated and a picece of copper is held in the vapor in a test tube. The copper and sulfur combine to a new substance, which can be recognized from the change in color, density and other properties.
29 lut 2008 · This demonstration involves some fantastic chemistry and makes an excellent introduction to the use of quantitative calculations to find the formula of a reaction product, copper sulfide. Students will also get the chance to see some of the allotropes of sulfur.
Copper oxidizes easily to form Cu 1+ and Cu 2+ ions. It reacts with oxygen in the air to form brown-black copper oxides, with CO 2 dissolved in rainwater to form green, and sulfur compounds to form copper sulfides.
