Paper chromatography Presented by – Miss. Shruti Vilas Kharat. SYBSc / FS13164 History- Paper Chromatography (PC) was first introduced by German scientist Christian Friedrich Schonbein (1865). PC is considered to be the simplest and most widely used of the chromatographic techniques because of its applicability to isolation‚ identification and quantitative determination of organic and inorganic compounds. Definition- Paper chromatography is an analytical method technique for separating and

OLD COINS TURN TO GOLD DESIGN: Problem or Research Question: How does zinc effects the color change in a copper penny? Hypothesis: If copper and zinc comes together‚ then it will form brass‚ which gives gold color to copper penny. Variables: There were no variables at this experiment PROCEDURES: Materials: Zinc (SN) filling‚ 3M NaOH solution‚ Copper penny‚ tongs‚ Hot plate‚ 100 ml beaker‚ 250 ml beaker‚ Bunsen burner‚ Water‚ Spoon. Procedure: First‚ we turned on the hot plate.

Lauren Sullivan Plants Imperfections Abstract The purpose of this experiment was to plant different crosses and observe the different phenotypic ratios the plants present. The procedure of this experiment was plant six different crosses and water them correctly so that we could observe the different phenotypes and compare them to Mendel’s proposed ratios. Mendel‚ who had studied peas‚ did a similar experiment and came up with specific ratios that a monohybrid and dihybrid cross should show. His

favorite candies? Chromatography can solve that for you. Chromatography is a separation technique used by scientists for separating both organic and inorganic compounds. There are four different types of chromatography: thin layer‚ liquid‚ gas‚ and paper‚ but for this lab paper chromatography will be used. Who invented chromatography? A Russian botanist named Mikhail Semyonovich Tsvet invented chromatography in 1901 while doing research on plant pigments. Why is chromatography so important? This

From the table‚ the result of dehydration of secondary alcohol is expected‚ and it undergoes E1 elimination. As supposed in the theory and mechanism‚ because elimination can occur both sides of secondary carbocation‚ so there are three products: 1-butene‚ trans-2-butene and cis-2-butene with three peaks. The main product is trans-2-butene‚ because it is the most stable compound. However‚ the result of dehydration of primary alcohol is not expected. It is supposed to form only one product‚ 1-butene

Separation of the Components of a Mixture General Chemistry 1 (Chem 101)‚ ISP SCUHS Report 2 January 26‚ 2014 Abstract The analyses of mixture were to distinguish and identify homogeneous mixture by using the techniques of decantation and sublimation. By performing these techniques‚ we examined our solutions such as SiO2 (sand)‚ NH4Cl (ammonium chloride)‚ and NaCl (sodium chloride) and mixed H2O (water) with each solution after being heated. After examining our solutions‚ we made calculations

PAPER and COLUMN CHROMATOGRAPHY REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids.
