Chromatography of Dyes
Essay title: Chromatography of Dyes
ABSTRACT
Separation and identification of components of a mixture was determined by using Chromatography. The components of a mixture have different affinities for a stationary phase as well as different affinities for a mobile phase.

INTRODUCTION
An extremely common technique by using two chemicals and filter paper can give you sufficient information. A well-done Chromatography of dyes will provide you with enough data to determine if a liquid mixture is heterogeneous or homogenous . In a learning activity you can separate and possibly identify food dyes in some drinks mixes and food colors. The effect of solvent polarity or the ability to separate and elute compounds will also be demonstrated. In this experiment you will need to use the equation Xcm/Acm=RF value. The length of A, is the length of the longest line of the food dye or food coloring. The Length of X is the length of all the other variables. In the experiment the lengths will be measured in Centimeters.

Experimental Procedure
You will need to obtain a piece of standard filter paper approximately 10*15 cm. Use a pencil to draw a line parallel to one of the longer edges, about 1 cm from the edge. Make 10 dashes on the pencil line, be sure to have them evenly distributed. At this point you will spot each of the 5 standards on separate dashes. Be sure to write down which liquid is at which dash. Then choose two food colors and two drink mixes, and spot them on the remaining four dashes. Curl the filter paper into a cylinder, make sure colors out, and staple the edges together. Do not allow the edges of the filter paper to overlap. Add approximately 10
