In a concentrated solution, which statement is correct?
A
A relatively large amount of solute dissolved per given amount of solution (or solvent)
B
A relatively small amount of solute dissolved per given amount of solution (or solvent)
C
No solute present; only pure solvent
D
Exactly the maximum possible amount of solute dissolved at a given temperature (a saturated solution)
Verified step by step guidance1
Understand the definition of concentration in a solution: it refers to how much solute is dissolved in a given amount of solvent or solution.
Recognize that a 'concentrated solution' means there is a relatively large amount of solute present compared to the solvent, but it does not necessarily mean the solution is saturated.
Differentiate between 'concentrated' and 'saturated': a saturated solution contains the maximum amount of solute that can dissolve at a specific temperature, while a concentrated solution simply has a high amount of solute but may still dissolve more.
Eliminate options that describe a small amount of solute (dilute), no solute (pure solvent), or exactly the maximum solute (saturated), since these do not match the general meaning of 'concentrated'.
Conclude that the correct statement for a concentrated solution is that it contains a relatively large amount of solute dissolved per given amount of solution or solvent.
