Multiple Choice
Salt water is best classified as which type of aqueous solution?
A
Basic solution (produces as the primary solute species)
B
Electrolyte solution (contains dissolved ions)
C
Nonelectrolyte solution (contains only neutral molecules)
D
Acidic solution (produces as the primary solute species)
Verified step by step guidance1
Understand the definitions of the types of aqueous solutions: a basic solution produces hydroxide ions (OH\-), an acidic solution produces hydronium ions (H\_3O\+), an electrolyte solution contains dissolved ions that conduct electricity, and a nonelectrolyte solution contains only neutral molecules and does not conduct electricity.
Recognize that salt water contains dissolved salt, which dissociates into its constituent ions (such as Na\+ and Cl\-) when dissolved in water.
Since salt dissociates into ions, salt water contains charged particles that can move freely in solution, allowing it to conduct electricity.
Because salt water contains ions but does not primarily produce OH\- or H\_3O\+ ions, it is neither a basic nor an acidic solution in this context.
Conclude that salt water is best classified as an electrolyte solution because it contains dissolved ions that enable electrical conductivity.
