You work in a research organization that is looking for markers of various diseases that can be used as a diagnostic for the disease. It has been reported in the past that high levels of Cu are found in the sweat of people with cystic fibrosis. One of the research projects is focused on looking for high levels of Cu in samples that can be obtained non-invasively such as saliva, sweat, hair, nails, etc. The lab will analyze large samples for Cu. What instrument would you recommend purchasing to support this work, Atomic absorption spectrophotometer or an inductively coupled plasma atomic spectrophotometer? Explain the basis for your decision.

Answer questions 3 and 4

Please answer the following question about a lab experiment about synthesizing aspirin. The procedure for this experiment is included in the photos. Compare the appearances of the crude and recrystallized Aspirin, what are the reason for these two to appear different?

2 K₂Cr₂O7 (aq) + 8 H₂SO4 (aq) + 3 C₂H5OH(aq) --> 2 Cr₂(SO4)3 (aq) + 2 K₂SO4 (aq) + 3 CH3COOH (aq) + 11 H₂O (1) The above reaction is what occurs in a breathalyzer test. The ethanol (MM = 46.08 g/mol) reacts with the dichromate ion in potassium dichromate (MM = 294.20 g/mol) to produce the green chromate ion in chromium sulfate (MM = 392.21 g/mol). The sample is analyzed in a hand-held spectrophotometer, and the amount of light transmitted is converted into an electrical signal. The signal is then converted to an absorbance value which is proportional to the amount of ethanol in a sample. Calculate the grams of chromium sulfate formed from 0.0250 g ethanol. Enter the value with no units.
