CH 12-13 REVM NAME_________________
USE THIS KEY FOR THE FOLLOWING
A increases b decreases c does not effect
Increasing pressure_______ solubility of a gas in a liquid
Increasing temperature _______ solubility of a solid in a liquid
Increasing temperature_______ solubility of a gas in a liquid
Decreasing surface area _____ the rate of solution
Dissolving a solute ______ the freezing pt of a solution
Dissolving a solute ______ the boiling pt of a solution
Cooling a solvent _______ the rate of solution
As a solution evaporates, its concentration_________
Agitating (stirring) _______ the rate of solution
TRUE OR FALSE
Oil and water are miscible
An unsaturated solution can dissolve more solute
Like dissolves unlike
Alcohol and water are immiscible
Electrolytes conduct electricity when in solution
Precipitates are soluble
Glass in nonvolatile
Distilled water is used for solutions because it contains necessary minerals
Concentrated is the opposite of dilute
Concentration is measured with molarity and molality
Molarity is measured in grams per mole
