You can learn how to use a pipet and pipet bulb on the Pipet page in the Techniques section of this website. The HCl solution and ketone can be conveniently measured from two different burets. Note that 10 mL burets are graduated differently than 50 mL burets. Divisions are marked every 0.05 mL. When reading the buret, you should estimate the volume to the nearest 0.01 mL. You can learn how to use a buret on the Buret page of this site. By using two 10 mL burets, a Mohr pipet, and a 2 mL pipet, you will have separate measuring capabilities for the HCl, ketone, H2O, and triiodide, respectively. It is then unnecessary to rinse out the burets and pipets, except at the start of a series of runs. Using a spectrometer Your TA will give a brief demonstration of how to use a Spec 20 spectrometer at the beginning of your lab period. You can see what the instrument looks like and how to use it on the Spectrometer page in the Techniques section of this website.
