Proper Lab Notebook Keeping

Here, we show the laboratory preparation for 10 students working in pairs, with some excess. Please adjust quantities as needed.

• Put on a lab coat, splash-proof safety glasses, and nitrile gloves. You'll work in a fume hood because these acids are toxic and corrosive.
• Ensure that the lab has containers for concentrated acid waste, aqueous acid waste, and glass waste.
• Prepare a bottle of concentrated sulfuric acid for each student group. Measure 10 mL of 98% w/w sulfuric acid with a graduated cylinder and pour it into 20-mL bottles using a funnel. Tightly cap the bottles and label them with the solution name and concentration.
• Prepare a bottle of nitric acid for each student group. Measure 10 mL of 70% w/w nitric acid with a clean graduated cylinder and pour it into 20-mL bottles via a clean funnel. Cap the bottles and label them with the name and concentration.
• Set one bottle of nitric acid and one bottle of sulfuric acid at each hood.
• Place a bottle of methyl benzoate in a common hood.
• Put Pasteur pipettes and circular filter papers on a central bench.
• Confirm that the balance area has enough weighing boats, spatulas, and lab wipes for the class.
• Set out the following glassware and equipment at each student lab station (we suggest that students work in pairs):
