How fast a substance dissolves in a liquid.

• Rate of Dissolution

• Surface Area

• Aqueous Solution

• Solubility

The process of mixing a substance into a liquid so that it is dissolved.

• Concentration

• Dissolution

• Solubility

• Solvent

Match the following scenarios with their effects on the rate of dissolution.

• Cooling the solvent

• It first decreases, then increases

• Using a solvent at constant temperature

• It decreases

• Changing the solvent temperature from low to high

• It remains the same

• Heating the solvent

• It increases

Which factor does NOT affect the rate of dissolution?

• Temperature

• Surface area

• Agitation

• Color of the solute

Which does NOT affect the rate of dissolution?

• Luster

• Temperature

• Agitation

• Surface Area

Match the following

• movement

• More _____ = more exposure = faster rate of dissolution

• exposure

• Higher temp = higher rate of dissolution = higher ____

• kinetic energy

• more surface area = more ____ = increased rate of dissolution

Smaller grains dissolve faster than larger grains.

• True

• False

The grain size of a solute do not affects the rate at which it will dissolve in a liquid.

• True

• False
