Unit 6B(1)
The substance in which the solute dissolves
What is a solvent?
a substance with a lot of solute is said to be
What is concentrated?
What does putting a balloon in a freezer do
What is Deflate
What is a solution
The outcome of an solvent and solute
The substance being dissolved
What is a solute?
A substance that dissolves in oil has what kind of polarity?
Nonpolar
A solution that contains very little solute is considered to be
What is dilute?
How does temperature affect the solubility of a gas?
as temperature increases, the solubility decreases
Low solvent to solute ratio
unsaturated
A solution that has dissolved the maximum amount of solute
What is a saturated solution?
When salt is added to water it does what to the boiling point?
Raises the boiling point
What do you do to make a solution more concentrated
add more solute
How does temperature affect the solubility of a solid?
increasing temperature USUALLY increases solubility
What is Agitation
Stirring
Compounds that produce solutions of ions in water
What is an electrolyte?
Adding a solute to a solvent does what to the freezing point?
It lowers the freezing point of the solvent
What do you do to dilute a solution
add more solvent
What are two factors that affect the rate of solubility?
What are temperature, surface area, and stirring(agitation)
Heat increases or decreases solublity
Increases
A neutral molecule in which unequal electron sharing results in a slightly positive end and a slightly negative end
What is a polar molecule?
What affect does stirring salt in water have on solubility.
It increases how fast the water dissolves
When diluting a solution, what remains constant?
the amount of solute
How does pressure affect the solubility of a gas?
Pressure increases, solubility increases
Cold increases or decreases solubility
Decreases
