An ASA tablet was boiled in 1.0 M NAOH solution following the procedure in this experiment. The resulting mixture was filtered and washed quantitatively into a volumetric flask and diluted to volume. The mean of two absorbance measurements of the diluted stock solution at 530 nm was 0.215. The calibration curve for the ASA standards gave a best fit line of Absorbance = 0.083*(ppm ASA) + 0.002. Calculate the ASA concentration for this diluted solution of the tablet in ppm. State the answer to 1 place after the decimal point. Do not enter units.

The determination of iron in wines was carried out by atomic absorption spectrophotometry, using the standard addition method. To do this, 10 mL of wine were placed in five 50 mL volumetric flasks; then 0, 5, 10, 15 and 20 mL of a 10 ppm iron standard solution were added to each of them. Next, they were gauged with distilled water and the absorbance was measured, obtaining the values of 0.040, 0.062, 0.081, 0.102 and 0.125 respectively. Calculate the regression parameters and obtain the iron concentration in the wine, in µg / mL.
Following the experimental procedure, a student combined 5.00 mL of 0.0020 M Fe3+ and 1.00 mL of 0.0020 M SCN- with 4.00 mL of water to create their Trial 1 solution. The student used their spectrophotometer to measure the absorbance of the reaction mixture and recorded an absorbance of 0.095. Find the following: Hint: The extinction coefficient of FeSCN2+ is 4,630 M-1*cm-1 and the cuvettes we use have a path length of 1.0 cm. The equilibrium concentration of Fe3+: M (give as decimal to nearest 0.000 001 M) The equilibrium concentration of SCN-: M (give as decimal to nearest 0.000 001 M) The equilibrium constant K: (give to nearest tens place)
In order to obtain better separation of the mixture, the above analysis was repeated using an HPLC technique. The retention times of compounds A and B were found to be 15.25 and 16.80 min, respectively, on a 40-cm packed column. An unretained species passed through the column in 1.25 min. The peak base width for A and B are 1.15 and 1.27 min, respectively. Calculate: i) The column resolution. ii) The average number of plates in the column. iii) The plate height. iv) The length of column required to achieve a resolution of 1.5.
A student weighed out 0.150 g of protein powder and dissolved it in 100 mL of water (Solution 1). The student then diluted this solution by transferring 1 mL into a 25 mL flask and diluting with water (Solution 2). Finally, 1 mL of that solution was transferred to a test tube and combined with 4 mL Bradford reagent. The absorbance of the solution in the test tube was 0.144. Assuming that the best fit linear line of the standard curve was y=0.04144x+0.01521 (μgmL), calculate the percent protein by mass in the original protein powder.

Maria was tasked to determine the concentration of a Fe2(SO4)3 solution. She prepared 5 different standards of Fe2(SO4)3 using the table below as her guide. She ran the standards and the unknown solution through UV-VIS spectroscopy and recorded the absorbances of each solution. HINT: use the dilution equation to determine the concentration of Fe2(SO4)3 in each test tube before preparing the standard curve. NOTE: No need to force the line to pass through zero. Just graph the data as is. What is the slope of the line of the standard curve from the given data? What is the concentration of the unknown solution?
A 0.0200 gram blood sample was decomposed by a microwave digestion technique followed by dilution to 100.0 mL in a volumetric flask. Aliquots of the sample solution were treated with a lead complexing reagent and water as follows: Solution 1: 10.0 ml blood sample + 20.0 mL complexing agent + 30.0 mL H20. Solution 2: 10.0 ml blood sample + 20.0 mL complexing agent + 26.0 mL H20 + 4.00 mL of 78 ppb Pb2+ standard. The resulting solutions were analyzed by UV/Vis at 375 nm. Absorbance for solution 1 = 0.155 and for solution 2 = 0.216. Calculate the concentration of lead (ppb) in the original sample.
A spectrophotometric method for the quantitative determination of the concentration ofPb2+ in blood yields an Ssamp of 0.133 for a 1 mL sample of blood that has been diluted to 6 mL. A second sample is spiked with 1 µL of a 1467 ppb Pb2+ standard and diluted to 6 mL, yielding an Sspike of 0.491. Determine the concentration of Pb2+ in the original sample of blood.

A 5.00-mL sample of blood was treated with trichloroacetic acid to precipitate proteins. After centrifugation, the resulting solution was brought to pH 3 and extracted with two 5-mL portions of methyl isobutyl ketone containing the lead-complexing agent APCD. The extract was aspirated directly into an air/acetylene flame and yielded an absorbance of 0.527 at 283.3 nm. Five-milliliter aliquots of standard solutions containing 0.400 and 0.600 ppm of lead were treated in the same way and yielded absorbances of 0.396 and 0.599. Find the concentration of lead in the sample in ppm assuming that Beer’s law is followed.
You are developing a procedure for determining traces of copper in biological materials using a wet digestion followed by measurements by atomic absorption spectrophotometry. In order to test the validity of the method, you obtain a NIST orchard leaves standard reference material and analyze this material with your procedure five times and obtain a mean of 12.27 ppm with a standard deviation of 0.097 ppm. The NIST sample is listed as 11.7 ppm. Does your method give a statistically valid value at the 95% confidence level?
