Next, rinse your hands by placing them under the warm water, holding your hands lower than your elbows allowing the water to remove all soap from your hands, being careful not to touch the sink. Keeping your hands lower than the elbow will allow all soap and germs to flow off your hands easily rather than flow up the arm. Remember, the sink can be contaminated and have germs on it, so avoid touching it and re-infecting your hands. Finally, dry your hands with a paper towel thoroughly and use the paper towel to turn off the faucet before you throw it away.

If the ink you are testing does not spread out, re-test it using rubbing alcohol. 8. Repeat this process for each strip and compare your results. 9. Let the strips dry and tape them on a sheet of paper as a record of the different pen types.
Dip the slide into Eosin solution for 7 times and remove the excessive solution with a paper towel. 3. Dip the slide into new methylene blue for 9 times and remove the excessive solution with a paper towel. 4. Use the incinerator to allow it to dry completely.
2. Use the sterile cotton swab to create a lawn of P. anvenginosa on 2 of the plates of Mueller-Hinton agar aseptically. 3. Using sterile forcep, pick key lime discs, and place them on opposite sides of a petri dish containing P. anvenginosa, with the code side facing up. Tap them gently with sterile forceps to stick them to the agar.
The third test will utilize thin layer chromatography to evaluate the purity of the aspirin as well as testing for the presence of leftover salicylic acid or other by products of the reactions. Experimental: Week 1: For the synthesis of the aspirin, 250 mL of water was boiled. 1.5 g. of salicylic acid were poured on a test tube. Then, 3.5 mL of acetic anhydride and four drops of 85% phosphoric acid were added. A cotton ball was placed to prevent vapor escape.
Pull the front of the pamper up out keep it laying flat. Carefully unfold flaps on the old pamper. take about 2 wipes , and carefully wipe the baby's area until clean. Place the wipes in the front part of the old pamper. Lift baby bottom up.
The extraction process is when a solvent, dichloromethane (15mL) is added to the filtrate in a separatory funnel; the mixture is gently swirled together 3 times, and stopcock is released in between to vent the funnel. Dichloromethane (including the emulsion) is then drained from the bottom into a 50mL Erlenmeyer flask. Same extraction process is repeated on the same filtrate and the dichloromethane is, once again, let out to the same 50mL Erlenmeyer flask as before. The combined dichloromethane solution and water (20mL) is poured into a rinsed separatory funnel. Mixture is gently swirled and drained out into an Erlenmeyer flask.
Gravimetric Determination of Sulfate Purpose The purpose of this lab is to determine the percentage of sulfate in the hydrate by precipitating the sulfate as barium sulfate. Materials Filler paper Sodium sulfate Graduated cylinder Bunsen burner Watch glass Beakers (250 mL, 400 mL) Rubber bulb Graduated pipette Beaker tongs Funnel Filter Paper Sodium Sulfate Drying oven Wash bottle Stirring rod Silver nitrate Hydrochloric acid Distilled water Small test tube Procedures First, .4861 grams of sodium sulfate was placed into a clean 400mL beaker. Exactly 200mL of water and 1mL of HCl was added to the same beaker. A watch glass was placed on the beaker and the solution was heated using the Bunsen burner to a gentle boil. The watch glass was removed with the beaker tongs.
