Chemistry: Copper Sulphate Calibration

Introduction The hypothesis for this experiment is the more concentrated a given solution is, the more light is absorbed. Through the results recorded and calculated from the practical, the hypothesis will be proved or disproved. Beer’s Law states that absorbance and concentration are directly proportional. “The Beer-Lambert equation shows that if the concentration of absorber doubles, the absorbance of the solution also doubles.” (Lewis & Evans, 2011). Through this experiment, this statement will be tested. Experimentally this conclusion is only...
