Chem 120 Solutions Chapter 7 Questions
with correct answers
Solution - Correct answer is a uniform mixture that may contain solids, liquids or gases (AKA a
Homogenous mixture- mixture that APPEARS to be a single substance)
_____________= Solute + solvent
Solvent - Correct answer the substance in greater abundance in the solution
(dissolves the solute)
example) Water
Solute - Correct answer The substance that is the lesser amount in the solution that is dissolved in the
solvent.
Example) Sugar, Salt etc.
What is the universal solvent? - Correct answer WATER
The Characteristics of Solutions - Correct answer *Soluble*- solutes ability to dissolve in a solvent
*Insoluble*- solute not able to dissolve in a solvent
*Immiscible*- two liquids that can be mixed together, but separate shortly after you stop mixing them
*Miscible*- two liquids that are soluble in each other
Suspensions - Correct answer A mixture containing particles that settle out if left undisturbed.
-particles are too large to be absorbed
-particles are greater than 1000nm in diameter
-they CAN be filtered
Examples:
Muddy water, many 'liquid' medicines that require 'shaking', Italian salad dressing
