EXPERIMENTAL
For Part A of the experiment, 50 mL of 0.05 M acetic acid solution was prepared with the use of the 0.5M acetic acid the stock solution. To star, 45 mL of deionized water were poured into a 150 mL beaker that was labelled “0.05 M acetic acid.” A 10 mL graduated cylinder was used to add 5 mL of 0.5 M acetic acid to the beaker, and the solution was stirred with a glass stirring rod, which was clean each time after use to . Then, a 100 mL of 0.5 M NaOH solution were prepared with the help of a 50 mL graduated cylinder to add 90 mL deionized water to a 250 mL beaker labelled “0.05 M NaOH.” A 10 mL graduated cylinder was used to add 10 mL of 0.5 M NaOH to the beaker, and the solution was stirred. After, the LabQuest and pH probe were prepared for data …show more content…
“Sensors” and “Events with Entry” were selected after the pH probe was plugged into Channel 1. After that, in the Name box, “Volume” was typed into the designated box, and the corresponding units, “mL,” were also added. All changes made were saved. To proceed, the burette was “conditioned” after it was secured the ring stand, and the stopcock was closed in order to add 10 mL of deionized water to clean and rinse the inside of the burette. This procedure was done twice with water, and another two times with the prepared NaOH solution. A plastic funnel was used each time to pour any given liquid into the burette, and after, before recording the volume, the funnel was removed. Then, the burette was filled with the NaOH solution previously prepared without surpassing the 0 mL mark, the volume was recorded to the nearest 0.05 mL. After that, 50 mL of deionized water and stir bar were then added to a 250 mL beaker. A 10 mL volumetric pipette was used to add 10 mL of acetic acid to the beaker, before placing the beaker on a stir plate to stir
