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

Chromatography of Food Dye Chem 180-DL3 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: In this experiment a 50mL beaker was filled with luke warm water and a pinch of salt water was dissolved in it

PAPER and COLUMN CHROMATOGRAPHY REPORT 1. 2. The unknown code is an amino acid‚ Glycine. To justify the reason is because the retention factor is the same exact number as the Glycine. The data of the unknown shows everything to be exact with the data of the Glycine 3. The mobile phase is the more polar during the capillary action of the experiment. As soon as the paper touches the mobile phase‚ the solvent rises to the amino acids. This is where you can find polarity of the amino acids.

photosynthetic pigments and has a higher energy wavelength than red light‚ we predicted that juniper needles placed in blue light would photosynthesize faster than juniper needles placed in red light. We measured the rate of change in CO2 concentration due to juniper needles. For each sample‚ we placed the needles into a chamber connected to the CO2 monitor and measured the rate of change of CO2 concentration for 10 minutes under red light and then 10 minutes under blue light. We ran three independent
