for Preparing Acid Solutions NOTE: Collect about 40 mL of 0.5000 M H2SO4 in a clean, dry 50 mL beaker. Additional acid may be obtained as needed. Draw 10.00 mL of 0.5000 M H2SO4 into a pipette from acid in a the 50 mL beaker. Transfer into a 250 mL Erlenmeyer flask. Add 3 drops of phenolphthalein to the acid solution in the flask. Mix by swirling. NOTE: Repeat this procedure, preparing three identical solutions. Review pipetting from Experiment 1. |
