What is a
solution?
Why isn’t water a
solution?
What are the
parts of a
solution?
Which do you
add more of..
solute or solvent?
Why is water
called the
universal
solvent?
What does it
mean for
something to
have solubility?
How can you
measure
solubility of a
substance in
water?
Solution – a homogeneous mixture of very small particles
the mixture does not separate out by letting it stand or by filtering
the particles are evenly spread out
Tap water is a solution.
Pure water is not a solution…..
… Because Solutions are mixtures.
There are 2 parts to a solution:
1. Solute – the part that gets dissolved
2. Solvent – the part that does the dissolving. There is more of the
solvent.
Water is called the “universal solvent” because it dissolves so many things.
If you have a solution, you have a solute with some degree of solubility
1. What is solubility?
Solubility is the property that substances have of dissolving in
solvents, such as the solubility of salt in water.
What is meant by the solubility of a material in water?
How much of the material dissolves in the water.
Can you calculate the
saturation point for a solute in
solution?
