Students will design a laboratory procedure to analyze the amount of copper in brass using a spectrophotometer. Students identify the correlation among wavelength, absorbance, and concentration for each of three possible ions that may be obtained from brass: copper, zinc, and iron. The activity contains enough materials for 15 groups of students as well as a Teacher’s Guide and Student Study Guide Copymasters.
