The error that has been made by student in the setup should be determined. Concept introduction: Distillation is a liquid-gas separation technique for two or more liquids on the basis of their difference in boiling temperature or vapor pressure.Vapor pressure is pressure exerted by vapor phase of liquid produced due to an increase in the molecular kinetic energy of the liquid phase or due to the increase in temperature. The temperature at which atmospheric pressure exerted on liquid equals to its vapor pressure is known to be its boiling point. Vapor pressure of the component decide boiling point of any mixture. Impurities in the mixture might result in an increase or decrease of observed boiling temperature. The steps for distillation are as follows: In distillation, a round bottom flask is filled one-third or half full with the liquid compound to be distilled. If the flask is overfilled it might flow inside condenser attached to it. Then a distilling head is inserted into the round bottom flask and then a condenser is attached to the side joint of the distilling head from where the compound is collected in another smaller round bottom flask after distillation. A heat source is placed below the distillation flask. A thermometer is carefully inserted in the thermometer adaptor and is placed properly on the distillation head for measuring the boiling temperature of the compound being distilled.

environmental chemist working for the Environmental Protection Agency (EPA) was directed to collect razor clams from a heavily-contaminated river superfund site and analyze them for cadmium (Cd²+) content using graphite furnace atomic absorption spectrometry (GFAAS). The chemist dried the clams at 95° C overnight and ground them in a scientific blender, resulting in ~ 50 g of homogenized dry weight. A representative 61.00 mg sample was taken from the ~ 50 g of dry material and dissolved in 100.00 mL of 0.1 M HCI to create a sample solution. Using the method of standard additions, the chemist prepared five standard solutions in 100.00-mL volumetric flasks, each containing 5.00-mĹ aliquots of the sample solution. Varying amounts of a 87.0 ppb (ug · L-1) cadmium standard were added to each of the flasks, which were then brought to volume with 0.1 M HCI. The solutions were then examined for their Cd²+ content using GFAAS, resulting in the following absorbance data. Sample Vol. (mL) Cd2+…
