Question

There are two specific projects to choose from:

1) The Kinetics of Jello – Research both kinetics and the process of making gelatin. Using your

kitchen, conduct the experiment a minimum of 5 times to accumulate data and statistics and

write up your report. Note that a complete study of the kinetics of a system includes the orders

of the reactants, the Rate Law and Rate constant as well as the Activation Energy (Ea) and the Frequency Factor (A).

2) Paper Chromatography and Intermolecular Forces of Plant Pigments – Research Plant Pigments,

Chromatography and Intermolecular Forces. Using your kitchen, conduct the experiment a

minimum of 5 times to accumulate data and statistics and write up your report. Note that a

complete study should include at least 10 different plant types and a method by which to

separate and identify them by chromatography.

Need to know a procedure for one of these experiments! This isn't to get the paper written for me just help me with the backgrounds on the topics for my paper as well as the procedure and what results to expect. I am just confused on how to set up the experiment and what to do.

Explanation / Answer

CChromatography is a technique used to separate the components of a mixture. The mixture is mounted on a support called stationary phase. For example in paper chromatography paper is used as stationary phase. The mixture in mounted at about 1cm above the bottom of stationary phase. After mounting the mixture on stationary phase the stationary phase is put in a solvent. This solvent is called the mobile phase. Minimum solvent should be used so that the solvent shoul not touch the mixture. The mobile phase move up the stationary phase by capillary action. While moving upwards the components of mixture are also dragged upward. But the components of mixture move with differnt speeds. As a result these get separated. The different speeds of the components is because of different forces of attraction between the components and stationary phase.
