Give an examples where each method is used in an analysis. What is particulate gravimetry? When do we use this technique?
- The spectroscopic data in the table is generated with five solutions of known concentration. Concentration (M) 0.0133 m= 0.0266 0.0532 0.106 0.213 Absorbance 0.1271 What is the intercept of the linear regression line? 0.08531 0.5388 1.069 Use a spreadsheet program, such as Microsoft Excel, to graph the data points and determine the equation of the best-fit line. 1.954 What is the slope of the linear regression line formed by these points? M-1Can paper chromatography be used to separate and identify very volatile substances? Why? Please explain comprehensively.2. What is the basis for the separation of components of mixtures by paperchromatography?
- what is chromatography? Explain different types of chromatography and explain how to seperate compounds. indicate stationary phase mobile phase.True or False?Why? In ion chromatography a single column containing ion exchange resin allows separating all major ions dissolved in water. *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.
- What do you call the type of analytical method that relies on the absolute stoichiometric equivalences of balanced chemical reactions in order to compute the amount of analyte present in the sample? A Instrumental methods B Classical methods C) Oxidative methods D Blank Correction MethodsA formula calls for 0.6 mL of a coloring solution. Using a 10 mL graduated calibrated from 2 to 10 mL IN 1mL units, how could you obtain the desired quantity of the coloring solution by the aliquot method?
