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
