1. The concentration of strontium is being determined by atomic absorption using a N20 - acetylene flame and measuring absorption at 460.7 nm. Analysis of the pure sample results in an absorbance reading of 0.662. Analysis of the sample with the addition of 1000 ppm potassium results in an absorbance reading of 0.893. Explain why the addition of K to the sample increased the absorbance of strontium in the sample.

2. ] You make 150.0 mL of a copper(II) sulfate solution but forget to cover it before leaving for the day. The next class, you measure the volume and find that you only have 132.0 mL remaining. You didn’t record the initial concentration, but you measure the absorbance of the remaining solution at 620 nm and find that it is 0.386. You also construct the following calibration curve for CuSO4: Standard solution Abs620 0.50 M 0.424 0.40 M 0.336 0.30 M 0.247 0.20 M 0.159 (refer to image) a. What is the value for k (in Beer’s Law)?

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?
