Question

Which of the following will increase the solubility of a solute? (Select all that apply)

a
decreasing the surface area of the solute
b
stirring the solution
c
increasing the surface area of the solute
d
heating the solution
e
cooling the solution

Answer 1

b, d, and e.

Stirring the solution increases the solubility by agitating the solvent, allowing for better interaction between the solute particles and solvent molecules.
Heating the solution increases the solubility by providing more energy to the solvent molecules, causing them to move faster and allowing for better interaction with the solute particles.
Cooling the solution increases the solubility for some solutes by decreasing the kinetic energy of the solvent molecules, making them move slower and allowing for better interaction with the solute particles.
