Question

(Paper Chromatography)

1. What carrier solution might work well to separate newspaper inks? Why?

2. What carrier solution might work to separate different salts? Why?

3. What carrier solution might work to separate different fatty acids?
Why?

I really have no idea what the answers could be. I tried searching google but couldn't find much. Please help!!

Answer 1

1. The newspaper solution that would work best with inks is alcohol since alcohol can dissolve inks.
2. Water can be used to carry salts since salts are soluble in water.
3. Oils can be used to carry fatty acids since they're both hydrophobic substances.
