Q3. A stock bottle of copper sulphate (heptahydrate) is provided in each lab (note that this substance is harmful/toxic, so you should avoid ingestion or skin contact: clean up any spillages and do not pour any copper sulphate solution down the drains). On the sheet supplied in the exam will be a mass concentration (%w/v) and volume of copper sulphate solution to be prepared. Using a volumetric flask, make up this solution and measure its absorbance at 650nm in a spectrophotometer. Record your results below: Asso of copper sulphate solution........ [Note: after use, pour your solution from the cuvette into the labelled waste pot at the workstation].
