1. Many things can affect the evaporation of solvents during a
chromatography experiment. To allow researchers to compare
results across experiments under different conditions, scientists
use an R
f
value, that is the ratio of the distance the pigment
travelled to the distance the solvent travelled. This number
remains constant across trials. Calculate the R
f
value for each
pigment.
Activity 2: Leaf Disk Assay Overview
2. Write a hypothesis that the Leaf Disk Assay is designed to test.
