Answer to Question #143997 in General Chemistry for Javier

Question

Which solution has the higher osmotic pressure?

pure water

10% (m/v) starch solution

Answer 1

10% (m/v) starch solution has more osmotic pressure than pure water.

This is so because the more the number of solute particles dissolved, the higher the osmotic pressure, and pure water does not have any solute particles in it, so it doesn't have an osmotic pressure.
