Students Are To Use Information Found In Experiment 23 Pgs 25 36 Of Their Ch132l Laboratory Manual Along With The Dat 1 (82.72 KiB) Viewed 64 times

Students are to use information found in Experiment 23 (pgs 25-36) of their CH132L Laboratory Manual, along with the data provided to complete this assignment. Part 1 Introduction: Students should write an introduction that is a minimum of 500 words. The introduction should include at minimum a brief discussion on the following topics. (1) Why is it important to graph data? (2) Discuss the mathematical relationship between density and concentration. (3) What is the importance of accuracy in this experiment? (4) What is the importance of the calibration curve and what information does it provide. Part 2 Data Analysis: Students should use the information found in Experiment 23 (pgs 25-36) of their CH132L Laboratory Manual to complete Table 1. Each sample was made with a 0.400M NISO4 6H2O stock solution and has a final volume of 50.00 mL. With the completion of the Table 1, the student will then construct a calibration curve, solution concertation versus absorbance, in Excel or similar program. The graph should display the trend line, data table, axis titles including unit, chart title and student name. The graph and with trend line will be submitted with this assignment. Using the calibration curve constructed from the data in Table 1. The student will solve the following problems. All work and calculation must be shown in order to receive credit for the work. (1) A student determines that an unknown NiSO4 6H₂O solution has an absorbance of 0.458. What is the concentration of the unknown NiSO4. 6H₂O?
