Thin Layer Chromatography, also known as TLC, serves as a means of both separating and identifying substances. Chromatography comes in diverse variations, but a common feature is that there is a fixed and a moving element. In TLC, the silica gel on the tray constitutes the stationary phase, while the mixture under separation makes up […]
A desiccation reaction of an intoxicant consequences in an olefine. This type of reaction requires an intoxicant. an acerb accelerator and heat. Generally strong concentrated acids. like sulphuric acid and phosphorous acid. are used as the acerb accelerator. The acerb accelerator protonates the intoxicant. to do a much better go forthing group. Weakest bases make […]
Electrophoresis is the motion of dispersed particles relative to a fluid under the influence of a spatially uniform electric field. Gel electrophoresis Is a laboratory procedure used to separate biological molecules with an electrical current. In this lesson, we’ll review how agrees gel electrophoresis works and introduce the equipment necessary to perform an electrophoresis experiment. […]
Introduction Chemiluminescence is a method used to measure analyte concentration by detecting the optical emission from excited chemical species. This technique differs from atomic emission spectroscopy (AES) as it involves the emission of energized molecules rather than excited atoms. The emitted light bands in chemiluminescence are wider and more intricate compared to those observed in […]
Objective: To separate the components of unsweetened, grape flavored Kool-Aid. Procedure: Using two syringes, inject different concentrations of alcohol to extract red and blue dyes, and artificial flavoring. Data: Conclusion: Different dyes are shown when separated by different concentrations of isopropyl alcohol. Discussion of Theory: Chromatography, resolution and selectivity played major roles in making the […]
In column chromatography a mixture is dissolved in a solvent and poured over a column of solid adsorbent then eluted with the same or a different solvent. This method is often used for preparative purposes; when a relatively large amount of the mixture and the components need to be isolated. The two main pigments in […]
Abstract The goal of this experiment was to use different dyes to determine the Rf value. Chromatography is done to determine the presence of a mixture in a substance. In this experiment different dyes were used such as McCormick food coloring, M&M’s, Kool-Aid, and the dyes that came with the lab kit. Experiment and Observation […]
Through chemistry, the study of what objects are made out of, we use different methods for finding out things we do not know. Most materials in our world are mixtures. Very few materials are pure substances. The art of separating mixtures is important because it enables us to isolate pure substances. Mixtures are either homogeneous […]
Chromatography is a term used to define a set of laboratory techniques for the separation of mixtures. Through Chromatography we analyzed complex mixtures. In our recent lab we analyzed complex mixtures. The purpose of this lab was to find whether the water soluble or acetone soluble liquid traveled farther. In our recent ab we measured […]
