14
Tell how you can examine a substance to
determine if it is pure or not.
400
15
Add water and filter it
400
16
Water is an example of this part of a solution.
100
17
Water is a solvent.
100
18
If you make a solution with orange crystals and
water, the orange crystals are WHAT in the
solution?
200
19
The orange crystal is the solute.
200
20
If you mix 5 g of salt in 20 mL of water, what
will the MASS of the solution be?
300
21
The mass will be 25 g (20 mL of water 20 g)
300
22
How does a solution compare to a mixture?
400
23
A solution is a type of mixture - it is REALLY
well mixed (homogeneous)
400
24
When you pour a solution through a filter, what
passes through the filter?
100
25
Filtrate (the entire solution goes through)
100
26
When you pour a mixture with soluble and
insoluble substances into a filter, what DOES NOT
get through?
200
27
The INSOLUBLE substance
200
28
What is the substance that gets trapped on filter
paper called?

Residue/Insoluble
300

Daily Double
31
How can you get the solute out of a solution?
400
32
Evaporation
400
33
How can you tell if a solution is saturated?
100
34
You can see grains of solute in the solution.
100
35
If you start with copper sulfate and container
that have a mass of 29.8 g, add copper sulfate to
water until it is saturated, and find the new
mass of the copper sulfate and container to be
22.1 g, how much copper sulfate was added?
200
36
7.7 g of copper sulfate

37
When salt is added to ice, what happens to the
melting and freezing point of ice?
300
38
The melting point and freezing point (which are
the same things) of the ice goes down.
300
39
What would you expect the temperature of boiling
salt water to be 98ºC, 100ºC, 102ºC?
400
40
102ºC (adding salt raises the boiling point)
400
41
When salt water is boiling, which of the
following is happeningWater is evaporating,
Water is dissolving, Water is disappearing, or
Water is drying?
100
42
Water is evaporating
100
43
Look at the chromatogram. Which of the solutions
was not soluble in water?
200
44
3 - it doesnt spread, so it isnt soluble.
200
45
Which of the solutions in the chromatogram have
the same solute in them?
300
46
2 and 4 are the only ones you can tell just by
looking (their bottom solutes line up).
300
47
Describe what happened in a test tube where big
red crystals were mixed with water and the result
was a red, transparent liquid with a few red
grains on the bottom.
400
48
The red crystals DISSOLVED in the water (it was a
solute, the water was a solvent). The solution
became saturated so the last red grains didnt
dissolve. The crystals are more dense than water!

49
What is one thing that ALLOYS all have in common?
100
50
They are mixtures with at least one of the
substances being metal.
100
51
Would a solution be considered heterogeneous or
homogeneous?
200
52
Homogeneous (really well mixed, same throughout!)
200
53
The picture that shows up on a piece of
chromatography paper is called
300
54
Chromatogram.
300
55
The substance that moves the farthest on paper
chromatography is the one that has what property?
400
56
It is the most soluble.
400
57
What is an example of an alloy?
500
58
Steel, brass, etc
