Anna has a solid sample and did use an aqueous solvent to dissolve it. She observed that some of her solid-sample was remained undissolved. She then filters her solution to separate the liquid from the undissolved solid. She disregards the solid so that it won’t interfere the reactions that may occur in the solution. Out of that solution, five replicates were obtained and she took the analytical procedure at the same time and in the same way. In Anna’s procedure, what was her source of error?

PART ONE: Preparation of FECNS* Solution Prepare the two solutions in table 1 by accurately measuring the required volumes of distilled water and CNS into two labeled test tubes. The absorbance of the solutions must be measured soon after adding the Fe" solution from a buret. TABLE 1 Fe 5 ml 5S mL Solution Distilled Water CNS 2 mL Total Volume 3 ml 2 ml 10 ml 3 mL 10 ml In this part of the experiment you are to explore what the above quote means. As a PRELIMINARY Exercise, formulate a hypothesis as to what would happen under each of the following circumstances: 1. 1ml of 0.0020 M CNS' solution is added to the unused portion of solution 1 in the test tube 2. One drop of 0.20 M CNS solution is added to the unused portion of solution 2 in the test tube.
Which statement about the determination of the percentage purity of benzoic acid is correct? * A- Only sodium hydroxide solution can be used as the titrant in the volumetric analysis of benzoic acid. B- Analysing a benzoic acid sample that still contains some hydrochloric acid may yield an analyte percentage that is less than expected. C- Analysing a wet benzoic acid sample may yield an analyte percentage that is more than expected. D- All these statements are correct. E- None of these statements are correct.

Normal calibration curves are generally run in water (pure solvent). If there is something in your unknown sample "matrix" which affects the analytical signal, you'll report an incorrect concentration. In this situation you'll choose to run a "standard addition" calibration curve. Standard addition entails adding the same amount of unknown to each of your standard solutions prior to analysis. This transforms your independent variable from "concentration" to "added concentration". These leads to an entirely different calculation for your unknown concentration. A standard addition procedure can be used with any analytical method. In this problem we're conducting a fluorescence assay for a blood protein which is a cancer marker. For the following problem plot a standard addition curve from the data shown below, and calculate the concentration for your unknown. Your unknown number is: 770 Solution 1 is your unknown diluted 25:1 and has an intensity of 5.94 Solution 2 is your unknown…
The thiourea in a 1.455 g sample of organic material was extracted into a dilute sulfuric acid solution and titrated with 37.31 mL of 0.009372 M Hg2+ via reaction: 4(NH2)2CS + Hg2+ →[(NH2)2CS]4 Hg2+ Is this an example of total analysis technique or concentration technique? Explain.
22 Experiment 2 Chromatography 32. A student properly sets up a column chromatography experiment. Although the mixture is soluble in the mobile phase, the sample appears "stuck" at the top of the column and will not elute regardless of how much solvent is applied. What could be the cause of this prob- lem and what could the student do to try and achieve a successful separation? NA disolves in #20 Salt No maybe the compound NASI is to much an the solvent being #20 is to little Vodafo 3. A student performs a separation by TLC on a silica get plate that results in three spots. A red spot is measured 23 mm away from the original sample spot, a blue spot is 42 mm away, and a yellow spot is 49 mm away. The distance from the original spot to where the solvent stopped is 55 mm. a) Calculate the Re value for each component in the mixture.

Often, palnters mix blue and white palnt to lighten Its color. Which of the following statements below are true regarding how the presence of two pigments In a single unknown solutlon would affect the results of your experiment? O With two cations in solution, both cations can potentially react with the chosen test. O if there are two different results/ppt/color changes, there could be interference, making the identification very difficult. O For any available test that has two matching or simlar results, multiple tests will need to be performed in order to identify both pigments correctly O The two cations can react with each other to form a precipitate. Therefore, the cations are no longer available to react with the reagent added for a particular test making it very difficult, it not impossible, to identify the cations.
