Below are sample questions representative of the exercises included on this worksheet and related 9.18 Solutions, Solubility, and Concentration Patterns skill assessments:

Problem 1Difficulty: Mastery

A student says, 'Any solution with extra solid at the bottom is supersaturated.' Which correction is most accurate?

AA solution with any solid nearby must be pure solvent.

BExtra solid proves the liquid contains no dissolved solute.

CExtra solid after long stirring usually means the liquid is saturated, not supersaturated.

DSupersaturated solutions must always have visible solid on the bottom.

Solution & Explanation:Undissolved solid shows the liquid has reached the solubility limit. Supersaturated solutions are usually clear until crystallization begins.

Problem 2Difficulty: Mastery

Which example best disproves the statement, 'A dilute solution cannot be saturated'?

AA solution with 2 g solute in 100 g water when the solubility limit is 80 g/100 g water

BA beaker of pure water with no solute added

CA solution with 80 g solute in 100 g water when the solubility limit is 2 g/100 g water and solid remains

DA solution with 2 g of a low-solubility solute in 100 g water when the solubility limit is 2 g/100 g water

Solution & Explanation:A solution can be dilute in concentration but saturated if the solute's solubility limit is very low.

Problem 3Difficulty: Mastery

On a solubility graph, what does the curve itself represent?

AThe mass of the container at each temperature.

BThe saturation boundary: points on the curve show the maximum stable dissolved amount at each temperature.

CThe path of a stirring rod through the beaker.

DThe amount of solvent that has evaporated from every sample.

Solution & Explanation:The curve marks the solubility limit. Points below, on, or above it are interpreted relative to that boundary.
