Name the categories below for mixtures and classify the above examples into the following two
categories.
__________________is a mixture where the
components that make up the mixture are
uniformly distributed throughout the mixture.
Appears to look like one substance.
Ex:
_____________________:is a mixture where the
components of the mixture are not uniform
or have localized regions with different
properties.
Ex:
Classify the following examples into the appropriate category.
Oxygen, sugar, salt, baking soda, hydrogen, neon, gold, distilled water (H2O)

What is the difference between soluble and insoluble?
To make a glass of lemonade you dissolved
sugar and lemon juice into water. The
solute(s) is/are ____________________________
and the solvent(s) is/are ___________________
Solution
Is dissolved
Does the
dissolving
A dilute solution has _______________ solute
dissolved into the ______________
A concentrated solution has ___________ of
___________________ dissolved into the ______________________
A solution that can still dissolve more solute is called an ___________________________ solution.
A solution that cannot dissolve anymore solute is called a _________________________ solution.
If you write the amount of solute dissolved into a certain amount of solvent you would have
written the _______________________ of the solution.
If 33g of solute is dissolved into 50g of water what is the concentration of the solution?

Sam had 135mL of water in which he put 23g of sugar and then heated it to 37˚C. What is
the solubility of Sam’s solution? _________________
Convert Sam’s solution and compare to Sally’s solution of 17.1g/100mL @ 37˚C.
Which substance is more soluble at 60˚C?
What is the solubility of NaCl at 0˚C?
If you had 100g of each solute at 80˚C
which substance would be saturated?
How much solute of KNO3 is needed to
make a saturated solution at 0˚C?
Draw what the solubility of the gas CO2 on the graph. What is the connection to thermal
pollution?
Sam heard that water was called the _____________________ solvent, because he was told that
it dissolves many types of solute. To test this statement he took six different solutes and tried
to dissolve them into 100mL of water. He then did the same but used vegetable oil and
alcohol as the solvent.
The manipulated variable in this lab was ________________________________
The responding variable in this lab was _________________________________
