Isopropanol is a good extraction solvent for plant pigments as it breaks down cell walls and is miscible with the pigments. How can I determine if I only extracted chlorophyll a from my spinach leaf?
In this lab, we grind the spinach leaf and let it sit in isopropanol to extract the chlorophyll a. I have a graph for absorbance vs wavelength and absorbance vs concentration of chlorophyll a but I don't know how I can determine if I only extracted chlorophyll a from my leaf.

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...

For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2
For the preparation and standardization of NaOH with KHP im supposed to boil water for 1hr and 30 min to remove CO2....the problem is that if I don't boil it for that long and (30 min) b/c of not enough time but I put the water I boiled for 1/2 hr aproximately into a NaOH bottle with a CO2 absorber and stored it there for a few days. I would assume that I would have to boil the water again...but...
