A mixture is 2 or more substances that are combined
together that can be separated by _____________ means
(not chemically bonded together)
_______________mixtures – ____________ mixed
mixtures, “_____________” composition throughout
______________ mixtures– ____________ mixed
mixtures, “_____________” composition throughout
Which type of mixture are solutions?
 _____________________
Solutions have the same ____________, ____________,
and ______________throughout them
We call solutions the “_____________________”
If a solution is made from a substance dissolved in
________, it is called an _________________solution

To create a solution, one substance must
____________ in another substance

____________– the substance _________________
 When solids or gases are dissolved in liquids,
they are considered to be the solutes

__________– the substance ___________________
 When a liquid dissolves another liquid, the
liquid that has the largest amount is considered
to be the solvent
As a general rule of thumb, there is LESS _________
and MORE ______________in a solution

Solutions do not always involve a solid or gas
dissolving in a liquid


They are attracted to each other
because they have opposite
charges (like a magnet)

Animation
 What
can you do to increase the rate at
which solutes dissolve in solvents?

________________!

_________________


More solvent is brought in contact with the solutes,
which cause the particles to dissolve more quickly
If you make larger solutes smaller, you are increasing
the surface area of the crystals which allows the
solvent to surround it more easily
_________________

This speeds up the movement of the particles which
causes more of the solvent particles to bump into the
solute particles
