Analysis of Cu(II) ions in solution
In this experiment you will make up a standard solution of Cu2+(aq) ions, successively dilute it and use a spectrophotometer or a colorimeter to make a calibration curve. You then measure the absorbance of a solution containing an unknown concentration of Cu2+(aq) ions and determine its concentration by interpolation. This experiment uses copper(II) sulfate solution to introduce you to the use of a visible...
