Question 1

What happens when you add a solute to pure water?

Answer 1

It lowers the water potential and brings water molecules in - this pull in gives a negative water potential

Question 2

How does more solute effect solute potential?

Answer 2

The more solute present, the more tightly water molecules are held, the lower the tendency of water to move out. So a higher concentration has a more negative solute potential .
