Stirring the solution...

• decrease the rate of solubility

• Doesn't change the rate of solubility

• increase the rate of solubility

• None of the above

When you measure how fast a solute dissolves, you are measuring the

• amount of dissolving

• rate of particle movement

• amount of particle movement

• rate of solubility

The smaller the particle size results in a....

• increase in solubility

• decrease in solubility

• decrease in surface area

• increase in bond strength

Which of the following does not affect the solubility of a solute in a solvent?

• The rate of stirring

• The size of the solute

• The temperature of the solvent

• The amount of the colloid added
