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.
In this experiment, you will prepare copper metal from the reaction of aluminum metal with a solution of copper(II) sulfate (cupric sulfate). From the amounts of the reactants, you will determine which reactant is the limiting reactant, and from this amount, calculate the theoretical yield of copper metal.
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.
10 lut 2021 · Use your Beer’s law graph to determine the concentration of copper ions in this solution. Then determine the mass percent copper in the sample mixture. Assume that the other components in the mixture did not interfere in the absorbance reading.
A class practical which investigates the reversible reaction of hydrated copper(II) sulfate. Includes kit list and safety instructions.
1 kwi 2017 · In an experiment in school, we heated copper wire (Cu) and yellow sulfur powder together in a crucible. I was wondering why this reaction cannot produce Copper Sulfate. I know it produces Copper Sulfide but I want to know why don't oxygen from the air, sulfur, and copper combine to form copper sulfate.
In this simulation you will be reacting copper(II) sulfate with sodium sulfide to produce copper(II) sulfide, a black precipitate. After the reaction the solution can be tested to determine if there is an excess of either CuSO
