Spectroscopy and a Calibration Curve Prepare a series of standard solutions of the colored compound with known concentrations by diluting the stock solution with distilled water. Use volumetric flasks to ensure accurate dilutions. Let's assume we have a stock solution of potassium permanganate (KMnO4) with a concentration of 0.100 M (molar). We will prepare five standard solutions with the following concentrations by diluting the stock solution with distilled water: 0.020 M 0.040 M 0.060 M 0.080 M 0.100 M Measure the absorbance of each standard solution at the wavelength of maximum absorbance (λmax) using the UV-Vis spectrophotometer. Record the absorbance values. For 0.020 M: Absorbance = 0.150 For 0.040 M: Absorbance = 0.290 For 0.060 M: Absorbance = 0.440 For 0.080 M: Absorbance = 0.580 For 0.100 M: Absorbance = 0.730 Plot a calibration curve by graphing the absorbance values (y-axis) against the corresponding concentrations (x-axis) of the standard solutions.

A set of three replicate AAS measurements were made from the same calcium standard. Use the information below to determine the LOD for calcium analysis. ⚫ The standard was prepared by dissolving 0.020 g of CaCO, in acid and diluting to 1.000 L. ⚫ After blanking the instrument, the three absorbance readings from the standard were 0.101, 0.096, and 0.104. Hint: Determine the slope of a 'two-point' calibration plot using the blank and average reading of the standard; use the standard deviation of the 3 absorbance readings as s ( )4 ppm ( )3 ppm ( ) 1 ppm ( ) 0.2 ppm
Fluorescence intensity was taken of 2.0 mL of the 10 μg/mL quinine standard solution into five 25 mL volumetric flasks. Into one, place 1.0 mL of 0.05 M sodium bromide solution and dilute to the mark with 0.05 M sulfuric acid solution. Similarly, add 2.0, 4.0, 8.0, and 16.0 mL of the sodium bromide solution to the remaining flasks before diluting to volume with the sulfuric acid solution. Why did the fluorescence intensity decrease as the concentration of sodium bromide increased? Only typed and correct answer with explanation please
