Experiment: UV-Vis Spectrophotometry and Beer’s Law Absorption of Light of Dyes in Beverages 5 mL of a lemon soft drink was pipette into a 25 mL volumetric flask and diluted to the mark with distilled water. 8 mL of this diluted solution was pipette into a test tube, then 2 mL of distilled water was pipette into the same test tube. Analysis by spectrometry found that the concentration of yellow dye in the test tube solution was 4.7 x 10-5 M. Calculate the concentration of yellow dye in the original soft drink.

Experiment: UV-Vis Spectrophotometry and Beer’s Law Absorption of Light of Dyes in Beverages A calibration curve for the orange dye in a soft drink was obtained by plotting absorbance against concentration (M) for a series of solutions of known concentration. The slope of the calibration curve was 226 L/mol and the intercept was -0.011. The absorbance of an unknown soft drink was found to be 0.333 under the same conditions as the calibration curve. Calculate the concentration of the orange dye in the soft drink.

You have a solution with a concentration of 0.80 mM, and you put it in a cuvette with a 1.0cm pathlength. You read an absorbance of 0.400. What is the extinction coefficient of your analyte? Question 4 options: 0.50 mmole/L/cm 0.50 mmol/L (cm)-1 0.50 L/mmole/cm 0.50 mM cm
A 0.1 g amine-containing compound is dissolved in water then diluted to 100 mL. To get the concentration of amine in this compound, you subject it to spectroscopic analysis. So, you get 1 mL of the previously diluted sample then dilute it again to 250 mL for measurement. Then, you fill 3/4 of a 1-cm cuvette with this diluted sample then you run an analysis using an AAS. The recorded absorbance is 0.545 at 410 nm. Solve for the molecular weight of the compound. The molar absorptivity is 1.23 x 104 cm-1 mol-1 L.
Here is the protocol for a UV-Vis spectrophotometer to detect water and chlorine-carbon. 1.Dissolve the water and chlorine-carbon compounds in a solvent, such as water. 2.Prepare a standard solution of known concentration that is similar to the sample being measured. 3.Calibrate the spectrophotometer using the standard solution. 4.Measure the absorbance of the sample using the spectrophotometer. 5.Calculate the concentration of the compounds in the sample using the calibration curve obtained from the standard solution. How is the spectrophotometer calibrated with standard solutions? When is the blank solution placed in the spectrophotmeter?

Mass spectrometric measurements of zinc near the detection limit gave the following counts: 75.1, 68.2, 64.1, 93.5, 55.6, 70.8, 80.7, 72.3, 59.2, and 76.8. A blank solution was measured 10 times and gave a mean signal of 18 counts. A sample containing 1.20 µM Zn2+ gave a signal of 1 159 counts. What is the concentration detection limit for zinc?
A technique called “GCMS” is often used instead of simple GC analysis. This technique entails passing a sample through a gas chromatography instrument and replacing the standard GC detector with a mass spectrometer (the “MS” part). What advantages do you think GCMS has over GC as well as simple MS?
A 10.00 mL of natural water sample containing Ni2+ was pipetted into a volumetric flask and diluted to 50.00 mL with pure water. In the second 10.00 mL of natural water sample transferred into a volumetric flask, exactly 4.00 mL of a Ni2+ solution with a concentration of 5.99 mg/L was added and then diluted to 50.00 mL with pure water. The measured absorbance is A1= 0.436 and A2 = 0.663. What is the Ni2+ concentration in unit of mg/L in the natural water sample?
