Document Summary
To illustrate the synthesis of several copper compounds from metallic copper: Cu > cu(no3)2 > cu(oh)2 > cuo > cuso4 5h2o > cu. All initial copper will be eventually recovered as metallic copper as a pure substance. The goal had been achieved by the end where the end results reveal as a brown sand-like substance identified as broken down copper pieces/particles. Part 1 synthesis of copper (ii) nitrate and copper (ii) hydroxide. Part 2 synthesis of copper (ii) oxide. Part 3 synthesis of copper (ii) sulphate. The experimental methods for this lab are highly effective yet not as reliable. This is mainly due to the small initial mass of copper used to complete this experiment. Since there is a small initial mass, the potential in creating a deviation is significantly large. Common issues in this lab may include failing to quantitatively transfer substances properly. This also attributes to the potential in having a skewed end result.
