You make a Kool Aid drink using Kool Aid powder, sugar, & water & you notice your drink still has to much powder sitting at the bottom. What will happen if you add more water to the drink?

• decrease the solubility of your drink

• decrease the solubility rate of your drink

• increase the solubility rate of your drink

• increase the solubility of your drink

Which of the following factors affects the solubility amount & rate of solubility?

• temperature

• surface area

• agitation

• amount of solvent
