To Determine the Percentage of Copper in a Brass Screw Using a Computer Interface with a Colorimeter.
Horgan, Joan; Hedge, Robyn
Australian Science Teachers Journal, v43 n2 p40 Jun 1997
Year 11 students investigated the real-world problem of whether screws are really brass. It allowed them to use the colorimeter and computer interface in a way that was easily understood and models normal practice in testing laboratories. Screws were dissolved in nitric acid and their absorbance of red light was compared with a standard curve. (PVD)
