Use the pH meter to determine the pH and record the measurement in Table 5. Use a clean 10 mL graduated cylinder to measure and pour an additional 10 mL of Coca Cola® to Beaker F. We use nitrous often and will be sterilizing after each patient. How should we manage this? You will need to consider how often you are using nitrous –and how long your sterilization process will take.

Use the “cola” pipette to transfer another 5 mL of cola into the 10 mL graduated cylinder and add this to Beaker F (the solution should now have a total of 10 mL of cola) and measure the pH with the pH meter.
Weigh the beaker on a balance which allows you to determine the mass to the nearest tenth of a milligram (i.e. ± 0.001 g). Fill (use the pipette filler) and discharge the pipette as recommended, into the beaker, and determine the mass of water discharged by taking the difference.
Measuring buffer capacity when a strong acid or a strong base is added to buffer solutions. Obtain six 50 mL beakers. Label them 1-6. Obtain about 100 mL of 0.50 M acetic acid (CH3COOH) and 0.50 M of sodium acetate (CH3COONa).During this chemistry lab, you will use various pieces of laboratory glassware, e.g., beakers, Erlenmeyer flasks, volumetric flasks, transfer pipettes, micropipettes, burets and graduated cylinders. All of the glassware listed above can measure volume.Using a 5-mL pipette, pipette 5 mL of deionized water into the beaker and measure the new mass. After determining the mass of the water delivered, calculate the exact volume of the water added to the beaker. Repeat this procedure two more times by pipetting an additional 5 mL of water .

50 mL volumetric flask – 50 mL laboratory water; 50 mL beaker – 10 mL laboratory water; 10 mL graduated cylinder – 10 mL laboratory water; Using the same balance as before, record the mass of the glassware with the added water. Record its mass in the Data Recording Sheet. Pour the water from the glassware back into the 250 mL beaker and .In your lab notebook, create a separate data table for each piece of glassware used. Be sure to label and title each table so you can easily identify the information contained in each one. (For example, the table for the 150 mL beaker might look like the following: Table 1. Volumes and masses for 150 mL beaker Use a pipebe labeled cola and transfer 5 mL of Cola into a clean and dry 10 mL graduated cylinder. 11. Add the 5 mL of cola to Beaker F and swirl gently to mix. Measure the pH with the pH meter and Record the new pH of the mixture of CH3COOH/ CH3COONa buffer and 5 mL cola in Table 3 12. Rinse the pH meter with 10 mL distilled water. 13. three parts. In part one, a 10-mL graduated cylinder is used to accurately transfer 10-mL portions of the distilled/deionized water into pre-weighed 100-mL volumetric flask. In parts two and three, the same 10-mL volume of water, as in the part one, will be delivered by a 10-mL volumetric pipette and a 50-mL burette.
frequently use volumetric pipettes in this course, we will use them today as a way of accurately dispensing a fixed volume of water. Volumetric Pipettes Obtain a 25 mL volumetric pipette. The accuracy of these pipettes ranges from ± 0.01 mL to ± 0.06 mL depending on the “class” and size of .

Weigh the beaker on a balance which allows you to determine the mass to the nearest tenth of a milligram (i.e. ± 0.001 g). Fill (use the pipette filler) and discharge the pipette as recommended, into the beaker, and determine the mass of water discharged by taking the difference. Repeat step 4 until you have the results of four (4) such trials.
For the following exercise you will be using a serological pipette. Use a 5 ml serological pipette and a 100 ml beaker. Before you begin, weigh the empty beaker and record your results below. Now take the 5 ml pipette and transfer the following volumes of water to the beaker:1- Press the pipette into the pump with a slight twisting motion. 2- The pipette is first washed with water ,then rinsed several times with a little of the solution. 3- The pipette then filled to just above the mark , the liquid is allowed to fall to the mark . Use your clean pipette to deliver exactly 25.00 mL of the equilibrated water into the 125 mL Erlenmeyer flask. Touch the pipette tip to the side of the flask below the neck during delivery. Remember that the pipette is calibrated to deliver so that the last drop remaining in the tip of the pipette after delivery should not be blown out.
