this is a picture of data from an experiment were we put a drop of solvent on a peice of paper with a point. them we put the the point of the paper in the water so that the point was in 3mm. Then we let the water absorb into the paper for about 10 min. then we measured which pigment was most soluble and which was least by how far it traveled on the paper and how close it was to the bottom of the paper.
