RAI: Solutions

What is the rate of dissolution?

• The speed at which a solute dissolves in a solvent

• The amount of solute in a solvent

• The temperature of the solvent

• The size of the solute

Which factor does NOT increase the rate of dissolution?

• Decreasing the temperature of the solvent

• Increasing the temperature of the solvent

• Increasing the surface area of the solute

• Agitating the solution

How does increasing the temperature of the solvent affect dissolution?

• It allows the solute to dissolve more easily

• It decreases the rate of dissolution

• It has no effect on dissolution

• It makes the solute insoluble

What effect does increasing the surface area of the solute have on dissolution?

• It allows the solute to dissolve more easily

• It makes the solute dissolve slower

• It has no effect on dissolution

• It makes the solute insoluble

Why does stirring a solution increase the rate of dissolution?

• It increases the number of collisions between solvent and solute molecules

• It decreases the temperature of the solvent

• It reduces the surface area of the solute

• It makes the solute heavier
