To increase students' awareness of possible invisible pollutants in drinking water sources, students perform an exciting lab requiring them to think about how solutions and mixtures exist even in unsuspecting places such as ink they use alcohol and chromatography paper to separate the components of black and colored marker ink students witness first-hand how components of a solution can be.
Paper chromatography is a technique used to separate a mixture into its component molecules the molecules migrate, or move up the paper, at different rates because of differences in solubility, molecular mass, and hydrogen bonding with the paper.
The purpose of the experiment is to determine the specific types of pigments found in a beat leaf and in a spinach leaf by using paper chromatography and two solvents: water soluble solvent and lipid soluble solvent if a water soluble solvent is present, then there will be the movement of only the.
