An unsaturated solution is one that $\qquad$
a) contains no solute.
b) has no double bonds.
c) contains the maximum concentration of solute possible, and is in equilibrium with undissolved solute.
d) has a concentration lower than the solubility.
e) contains more dissolved solute than the solubility allows.
Solution
Solution Steps
Step 1: Understand the Question
The question asks us to fill in the blank regarding the definition of an unsaturated solution. We need to choose the correct option from the given multiple choices.
Step 2: Analyze Each Option
Option a) "contains no solute" - This describes a pure solvent, not an unsaturated solution.
Option b) "has no double bonds" - This is irrelevant to the concept of a solution's saturation.
Option c) "contains the maximum concentration of solute possible, and is in equilibrium with undissolved solute" - This describes a saturated solution, not an unsaturated one.
Option d) "has a concentration lower than the solubility" - This correctly describes an unsaturated solution, which can still dissolve more solute.
Option e) "contains more dissolved solute than the solubility allows" - This describes a supersaturated solution, not an unsaturated one.
Step 3: Select the Correct Answer
Based on the analysis, the correct option is d) "has a concentration lower than the solubility."
Final Answer
\(\boxed{\text{d) has a concentration lower than the solubility.}}\)
