Interpreting Data from Graphs Practice Test

PASSAGE I

CHEMISTRY: This passage is adapted from a study on the solubility of various substances in water.

Solubility is defined as the maximum amount of a solute (substance being dissolved) that can dissolve in a specific amount of solvent (usually water) at a given temperature. The solubility of most solids increases with temperature, while the solubility of most gases decreases with temperature. A student performed an experiment to measure the solubility of three solid salts—Potassium Nitrate ($KNO_3$), Sodium Chloride ($NaCl$), and Cerium(III) Sulfate ($Ce_2(SO_4)_3$)—and one gas, Oxygen ($O_2$).
