Define an unsaturated solution.
What is A solution that contains less solute than a saturated solution
100
Formula for concentration
What is Molarity= moles of solute/liters of solution.
100
Definition of:

100
The percent of water in the hydrate: NaCl * 4H2O
What is 55.2%
200
The amount of energy needed to raise the temperature of 1g of substance 1 degree Celsius.
What is specific heat capacity
200
Name 4 factors that affect the rate of dissolving.

200
Definition of:
What is A measure of the amount of solute that is dissolved in a given quantity of solvent
200
Formula
What is M1 * V1= M2 * V2
200
A hydrate.
What is something that removes the moisture from an environment.
300
The reason water expands when it freezes.
What is the water molecule rearranges its structure to that of a hexagon. The hydrogen bonds are rearranged so the center is open space, making the substance expand.
300
An aqueous solution of potassium sulfate is made. Name the solute and solvent.
What is

300
Calculate the number of grams needed to prepare this solution:
25L of a 4.5M stock solution of NaCl
What is 6574.84g of NaCl
300
You must prepare 450.0 mL of 0.550M NaBr solution using 2.00M NaBr stock solution. How many milliliters of stock solution should you use?
What is 123.75 mL of stock solution.
300
Define immiscible and give an example.
What is liquids that do not dissolve in one another.
ex: Varies
400
Explain how hydrogen bonding explains water's high boiling point
What is
Hydrogen bond is relatively strong attraction between molecules of water, which prevent molecules to escape from each other. Relatively high temperature is needed to break the bond (100°C)
400
ethanol and water is an example of what type of solution.
What is miscible
400
What is the molarity of a KOH with a volume of 3500mL of a 5.6 mole solution?
What is 1.6M of KOH.
400
In order to dilute 5.0 L of a 6.00M solution of NaOH to 0.750M solution, how much water must
you add?
What is 40L of water needed.
400
Define Supersaturation
What is A solution that contains more solute than it can theoretically hold at a given temperature
500
The formula for the hydrate: sodium sulfite pentahydrate
What is Na2SO4 * 5H2O
500
Capable of being dissolved (vocabulary word)
What is solubility
500
Find the mass in grams of a KOH solution with a molarity of 4.5M and a volume of 5600ml.

Define Henry's law, in words.
What is “At a given temperature, the solubility of a gas in a liquid is directly proportional to the pressure
of the gas above the liquid.”
