Making Copper Sulfate Experiment Youtube Fill a boiling tube with a 2 cm depth of sulfur. cut an 8 cm long piece of copper wire, weigh it and record the mass. gently heat a 2 mm diameter glass rod and shape it into a small glass hook that will hang over the lip of the boiling tube. hang the piece of copper wire over the hook, inside the tube. clamp the tube at its top in position. In the copper(i) sulfide, the copper is 1 and the sulfur 2. the oxidation states of the elements oxygen (in the gas) and copper (in the metal) are 0. in sulfur dioxide, the oxygen has an oxidation state of 2 and the sulfur 4. that means that both the copper and the oxygen have been reduced (decrease in oxidation state).
Experiment With Copper Sulfide Youtube 3. by burying the copper wire with plenty of sulfur and then heating the mix, the wire becomes completely submerged in liquid sulfur. the liquid sulfur then gets to react with the copper, and any oxygen that could possibly oxidize the copper would have to diffuse into the liquid sulfur before reaching the copper. In order to determine the empirical formula for copper sulfide (or for any compound, for that matter) you need to have some information about either the mass of one reactant and the mass of the product, or about the percent composition of the copper sulfide. for the first case, let's assume you are doing a lab experiment in which you heat a mixture of copper and sulfur in order to produce a. 6. sample calculations: in an experiment, a mixture of copper and sulfur was heated to produce a sample of copper sulfide. the following data were obtained: a. weight of the empty crucible 2.077 g . b. weight of the crucible copper 2.289 g . c. weight of the crucible copper sulfide 2.396 g. Copper sulfide is one of the most important metal chalcogenide, which has attracted much interest in the recent research due to its special properties and potential applications. copper sulfide has excellent metallic properties, and can be easily transformed into superconductors at about 1.6 k [1]. cus nanoparticles exhibit excellent physical.
