SECTION 1: SOLUTIONS AND SOLUBILITY FUNDAMENTALS
(Q1-15)
QUESTION 1
Which of the following best describes a homogeneous mixture?
A) A mixture containing multiple visible phases
B) A mixture with more than one component but only one visible phase
C) A mixture of two liquids that do not mix
D) A mixture where the solute is visible to the naked eye
Correct Answer: B
Rationale: A homogeneous mixture has more than one component yet only one visible
phase. The components are uniformly distributed at the molecular level .
, QUESTION 2
What is the process called when ions are surrounded by water molecules as an
ionic compound dissolves?
A) Dissociation
B) Ionization
C) Hydration
D) Precipitation
Correct Answer: C
Rationale: Hydration is the process in which ions become surrounded by water
molecules. This allows ionic compounds to dissolve in water .
QUESTION 3
The term for liquids that mix with each other in all proportions is:
A) Immiscible
B) Miscible
C) Saturated
D) Supersaturated
Correct Answer: B
Rationale: Miscible liquids mix with each other in all proportions to form a solution.
Immiscible liquids do not readily mix .
QUESTION 4
Which of the following correctly describes the general trend for solubility of solids
as temperature increases?
A) Solubility generally decreases
B) Solubility generally increases
