Solubility
Soluble
Sugar is soluble in water. Translation: Sugar dissolves in water. The solute particles are more attracted to the
solvent than they are to each other.
Examples?
Sugar is soluble in water.
Insoluble
Insoluble – not able to be dissolved in a particular solvent. Ex. Fat droplets in milk.
The solute particles are more attracted to each other than they are to the solvent.
Oil is insoluble in water.

Concentration
Concentrated Solution
(lots of solute)
Dilute Solution
(relatively little solute)
How do you describe what is in between?

Concentration
How do you know what to compare it to? We use numbers to describe how
concentrated or dilute something is. This is called the concentration. The concentration tells us exactly how
much solute is in a certain amount of solvent (or one tube of water).
