One way to determine the degree of saturation of a solid-liquid solution is to drop a crystal

A KNO₃ solution containing 45 g of KNO₃ per 100.0 g of water is cooled from 40 °C to 0 °C. What happens during cooling? (Use Figure 13.11.)

If more powdered kool-aid is added to the same amount of water, what happens to the solution?

A solution that contains less solute than a saturated solution at a given temperature and pressure.

The particles of matter that are dissolved in a solution are known as what?

Which term refers to a solution to which more solute can be added at the same temperature?

A solution contains 35 g of NaCl per 100.0 g of water at 25°C. Is the solution unsaturated, saturated, or supersaturated? (Use Figure 14.11.)
