Stacy runs a paper chromatography experiment using the same ink, but two different solvents. Using solvent A results in the ink separating into three bands, but solvent B does not carry the ink away from the original spot. Which of the following could explain the results?
- The Ink was a mixture, but only in solvent A
-Solvent A was not a good mobile phase because it could not dissolve the ink
-The ink was a pure substance and dissolved in both solvents
-Solvent B was not a good mobile phase cause it could not dissolve the ink
