Question
If the solubility of KCl in 100 mL of H 2O is 34 g at 20 °C
and 43 g at 50 °C, label each of the following solutions as
unsaturated, saturated, or supersaturated. If more solid is
added than can dissolve in the solvent, assume that
undissolved solid remains at the bottom of the fl ask.
a. adding 30 g to 100 mL of H 2O at 20 °C
b. adding 65 g to 100 mL of H 2O at 50 °C
c. adding 20 g to 50 mL of H 2O at 20 °C
d. adding 42 g to 100 mL of H 2O at 50 °C and slowly cooling
to 20 °C to give a clear solution with no precipitate
