1. In paper chromatography, is the substance being tested the solute or solvent? Explain your answer. 

I think the substance being tested is a solvent. I think this because it is being dissolved to form the ink on the filter paper. 

2. A bucket of paint spills on your classroom floor. How could you use your knowledge of dissolving to help clean up the paint? 
I actually have no idea. 

Can my number 1 question be checked, is it right? And for number 2, I need help.
