Determination of Cupric Sulfate Hydration Number

By: David Gould This experiment consisted of creating various concentrations of copper solutions, and measuring the absorbance of each in an atomic absorption spectrophotometer. The absorbances were used to create a calibration curve, the equation from which was used to calculate an experimental concentration for the unknown I was given. This was found to be 875.3 ppm copper for Unknown #1. Further calculations showed that this gave a hydration number of approximately 2, meaning the unknown was cupric sulfate dihydrate. […]
