Dilute Solution vs Concentrated Solution
dilute solution – mixture with only a little solute dissolved in the solvent.
concentrated solution – mixture with a lot of solute dissolved in the solvent.

Solubility
The maximum amount of solute that can dissolve in a specific amount of solvent usually 100 g.
g of solute
100 g water

Saturated vs Unsaturated
A saturated solution contains the maximum
amount of solute that can dissolve.
Un-dissolved solute remains.
If you can continue to dissolve more solute in
a solution then it is unsaturated .

A. Why would a bottle of carbonated drink
possibly burst (explode) when it is left out
in the hot sun ?
B. Why would fish die in water that gets too warm?

Answers
A. Gas in the bottle builds up as the gas becomes less soluble in water at high temperatures, which may cause the bottle to explode.
B. Because O2 gas is less soluble in warm
water, the fish may not obtain the needed
amount of O2 for their survival.
