Now that we've determined all sorts of ways we can
express the concentration of our solution,
we need to think about the differences in solubility between different compounds.
For example, sodium chloride dissolves really readily in water.
We can dissolve a lot of salt in water.
But there are other chemicals,
such as sand, that don't dissolve very well in water.
If we took a container of water and
dumped in a teaspoon of sand, it wouldn't look like any of it dissolves at all.
Where as if we took a container of water and we dumped in a teaspoon of salt,
as long as we had enough water we could stir it up and the salt would dissolve.
So there's different.
Amount of solute that can dissolve in solvent.
There's limits to the amount of a solute that will dissolve in a given type of
solvent, and that depends on the chemical composition of the solute,
the chemical composition of the solvent, the temperature
of the reaction mixture, and even the pressure of the reaction mixture.
For the most part we're going to assume that we're at room temperature and
normal atmospheric pressure at sea level.
