Description
A great introduction to separation science
- Learn how paper chromatography can separate a mixture
- Separate universal indicator and wet-erase markers with paper chromatography
- Calculate and interpret retardation factors
In this introductory kit, students are introduced to paper chromatography as a means for separating a mixture. They separate the components of a universal pH indicator to gain practice in chromatography technique. Then students separate the components of wet-erase markers and calculate the retardation factors. They use this data to understand how chromatography could be used to identify unknown components of a mixture. This activity requires approximately 70 minutes of classroom time, which can easily be divided between 2 class periods. Kit materials are sufficient for a class of 10 student groups.
