QUESTION 1
Two liquids that will dissolve in each other are said to be:
A) immiscible
B) miscible
C) hygroscopic
D) deliquescent
Correct Answer: B – miscible
Rationale: Miscible liquids mix with each other in all proportions to form a solution .
Immiscible liquids do not readily mix . For example, ethanol and water are miscible,
while oil and water are immiscible.
, QUESTION 2
A homogeneous mixture of two or more substances is best described as a:
A) heterogeneous mixture
B) solution
C) suspension
D) colloid
Correct Answer: B – solution
Rationale: A solution is a homogeneous mixture of two or more substances, with a
solvent and one or more solutes. In a solution, the components are uniformly
distributed at the molecular level .
QUESTION 3
The substance that is in greater quantity in a solution is called the:
A) solute
B) solvent
C) concentrate
D) solute
Correct Answer: B – solvent
Rationale: The solvent is the substance present in the greater quantity in a solution; it is
the medium in which the solute dissolves . The solute is present in the lesser quantity.
QUESTION 4
Which of the following correctly describes a concentrated solution?
A) A solution with a very small amount of solute
B) A solution with a relatively large quantity of solute dissolved per unit volume of
solution
