Question

a chemist dissolved crystals of an unknown substance into water at room temperature. he found that 33 g of the substance can be dissolved into 100 ml of water. what property of the unknown substance was the chemist most likely investigating?
(a) solubility
(b) rate of dissolution
(c) chemical reaction to water
(d) production of a chemical change

Explanation:

Solubility is defined as the maximum amount of a solute that can dissolve in a given amount of solvent (here, 33 g in 100 mL water) at a specific temperature (room temp). The other options: rate of dissolution relates to how fast it dissolves, thermal reaction to water involves heat changes, and reaction to temperature change would involve varying temp. Since the experiment measures how much dissolves, it's solubility.

Answer:

A. Solubility
