useful for different purposes. Many pigments found in nature can be quite effectively used as acid-base indicators. The purple eggplant peel‚ the dyes in the blueberries and the purple camote peel contain anthocyanins. These plant pigments produce definite colors in solutions of different acidity or basicity. Anthocyanins are also water soluble and have colors that are dependent upon the pH of the reacting solution. In our study‚ the researchers used a lampunaya leaf that also contains anthocyanins

Thin Layer Chromatography Introduction Thin Layer Chromatography or TLC is a technique used as a separation and identification technique. There are many forms of chromatography‚ but one thing that remains constant throughout all of the types of chromatography is that there is a stationary phase and a mobile phase. In the case of TLC the stationary phase is the silica gel on the TLC tray. Procedure Chromatograph method is a method of separating mixtures of two or more compounds. Two phases

the Kool-Aid was correct. However‚ solely based upon the Rf values‚ the dyes in the green Kool-Aid are Red 40 and Yellow 6 as those are closet Rf value to the numeric data collected and calculated from the Kool-Aid chromatogram. However‚ the chromatography paper in both trials display that the dyes in Kool-Aid are a form of yellow and a form of blue because one color band was of a blue tint and the other‚ a yellow tint. Therefore‚ based on this qualitative data‚ the dyes in the green Kool-Aid are

Separations: Chromatography of M&M and Ink Dyes Almost all substances we come into contact with on a daily basis are impure; that is‚ they are mixtures. Similarly‚ compounds synthesized in the chemical laboratory are rarely produced pure. As a result‚ a major focus of research in chemistry is designing methods of separating and identifying components of mixtures. Many separation methods rely on physical differences between the components of a mixture. For example‚ filtration takes advantage of substances
