Purpose: The purpose of this experiment was to learn the correct method of determining the mass percent of copper in a commercial brass alloy. As a pharmacist, there may be a time when I would need to check for the mass percent of a certain compound in a solution so learning this technique will be very beneficial. This experiment also allows me to become more familiar with certain equipment such as the spectrophotometer and the logger pro software. Procedure: Materials: Spectrophometer 1 50 mL graduated cylinder Laptop Logger Program 1 piece of copper wire 1 10 mL test tube 1 80 mL test tube 3 Volumetric pipettes (10 mL, 25 mL, 50 mL) 1 250 mL Erlenmeyer Flask 4 100 mL Flasks 1 250 mL beaker 100.0 mL of HNO 3 1. Plug in spectrophotometer into computer and connect it using the power cable. 2. Turn laptop on and click on the Spectro Pro (1.0) icon. 3. Clean test tube and rinse three times with 0.2 % nitric acid 4. Fill test tube half full with nitric acid 5. Wipe outside of tube with paper towel to remove fingerprints and droplets. Then insert
