nCH3 The first step in the lab is the preparation of the solvent used in the developing chamber for thin layer chromatography. The solvent used is a 3:1 mixture of toluene and petroleum. After the developing chamber is prepared‚ it is essential to begin preparation of the unknown DNPH derivative[6]. The preparation of the 1‚2 DNPH derivative of a ketone is in fact a small organic synthesis which produces a fraction of a gram of product. The second part of the lab makes use of NMR Spectrometry

Fast foods have become a common trend amongst many individuals. Most people would always say they don’t have time hence opt for fast foods. With the advancement of modern technology these foods are made in way that leaves questions unanswered. Despite research showing organic food such as meat and poultry serve better nutritious supplements‚ most people tend to rely on fast foods such as vanilla and‚ barbecue more so in U. S. A.

purpose of this lab was to determine the food dyes present in a selected beverage‚ their concentration‚ and then replicate the solution within a 20% margin of error. The beverage we chose was Gatorade Frost Riptide Rush. A spectrometer was used to determine which food dyes were present in the sampled beverage‚ red 40 and blue 1 were determined to be present. The next step was to determine the concentration of the dyes‚ this was done by testing the absorbance of the red 40 and blue 1 dyes at varying
