**13.** A solution of 10 grams KCl at 10 degrees Celsius is said to be:
**a) unsaturated**
This is based on the fact that at 10 degrees Celsius, the solubility of KCl in water is typically higher than 10 grams per 100 mL of water. Therefore, if only 10 grams are present, the solution can still dissolve more KCl.
**14.** A student is making a salt water solution for a lab experiment. Which of the following would increase the rate the salt dissolves?
**c) stirring the solution**
Stirring the solution increases the contact between the salt and the water, allowing more salt to dissolve faster.
