Pre lab
Introduction Your instructor has prepared an extract of chloroplast pigments from fresh green grass or fresh spinach. A blender was used to rupture the cells, and the pigments were then extracted with acetone, an organic solvent. Work- ing with one other student, begin this exercise by separating the pigments extracted using paper chromatography. To do this, you will apply the pig- ment extract to a cylinder of chromatographic paper. You will then place the ylinder in a jar...

2. If two different compounds have the same Rr value, how might they be identified using paper chromatography? 3. Why is it important to keep the spots on the paper as small as possible? 4. If the solvent pool at the bottom of the beaker touched the spots on the 1.5cm line, what would happen to the spots? How would you address this error? 5. If you were teaching a student how to do paper chromatography, what three pieces of...

Welcome to our plant sciences department here at TransBiol It's great to have you as an intern. I'm the lead scientist of a team developing new herbicides to use against invasive plant species. The team has been really swamped with work, so it'll be great to have some help analyzing all the data we're collecting. Since it's your first day, a great way to get started with any research project is to brush up on the background knowledge you'll need...

Chromatography: Separating Mixtures Introduction: Magic marker inks are often mixtures of several compounds. Paper chromatography is a common method of separating various components of a mixture. After separation, you can observe the different colors that make up a particular color of magic marker ink. You can also calculate a ratio Rf, which compares how far each compound traveled to how far each solvent (substance that dissolves another substance) traveled during the experiment. Rf = Ds/Df Ds = Distance traveled by...
