- functional grp analysis compound: myristic acidpls complete the table Test Reagent Observation Inference NaHCO3 Effervescence Br2 in water, dark Yellow solution 2,4-DNPH Orange solution KMnO4 Purple solutionA newly synthesized drug was found to have a carboxyl group, an imide and a sulfonamide group. The first type of method to consider in this drug molecule’s quantitatve analysis is: a. Non-aqueous Alkalimetryb. Non-aqueous Acidimetryc. Aqueous Alklaimetryd. Aqueous AcidimetryThis is a ATR spectrum. In which caffeine/PVA films were measured. Line a) correspond to a pure pva film and the other lines are films at increasing caffeine concentration. Notice that the OH band at around 3200cm-1 decreases at higher caffeine concentrations. However at a certain concentration (line d) such band starts to increase back to the initial intensity. What does that mean? Waht is the chemical meaning for that behavior?
- Calculate the concentration of a solution of peptide AWSME, in mM if the absorbance at 280 nm for the solution is 0.6 absorbance units, and a 0.2-cm cuvette is used.

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.

- What are the advantages of using the KBr in IR spectroscopic sample preparation? Please shortly answer at your own words. Answer should be to the point (specific 4-5 lines).A phenol standard with a concentration of 4.00 ppm has an absorbance of 0.424 at a wavelength of 460 nm using a 1.00-cm cell. A water sample is steam-distilled, and a 50.00-mL aliquot of the distillate is placed in a 100-mL volumetric flask and diluted to volume with distilled water. The absorbance of this solution is found to be 0.394. What is the concentration of phenol (in parts per million) in the water sample?The answer with a BCA table for both parts would be great, thank in advance for the help. btw, this is a pre test that isn’t graded
