CHE 117L Fall 2007 Name __________________________________ Lab section ______________________________ Experiment 3. An Introduction to Glassware and Technique Purpose This laboratory will introduce you to laboratory glassware and instruments, and teach you to use them with proper techniques. You will be instructed how to use an analytical balance, volumetric flasks and pipettes, burettes and a spectrophotometer. Then you’ll practice using them by performing a titration and colorimetric spectroscopy. Procedure 1) Using an analytical balance and a piece of weighing paper that you have folded to leave indentations for easier handling weigh out 0.5 g of colored powder. Add the powder directly (and carefully) so it slides from the paper down the fold line into a 50 mL volumetric flask and dilute to the mark with distilled water (Make sure to record your observations). 2) Using a 10 mL volumetric pipette, pipette 10 mL of your orange solution into a 125 mL Erlenmeyer flask. Repeat two times, labeling each flask (3 solutions total). Wash your pipette
