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 .

Affect of Temperature

Temperature Solubility (g/100 g H2O)

KCl(s) NaNO3(s)

0° 27.6 74

20°C 34.0 88

50°C 42.6 114

100°C 57.6 182

The solubility of most solids increases as temperature increases.

Learning Check

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?

Page 14: Do NOW Textbook Open your textbook to page 407 Answer all of the questions – compare your answers with your table group. Review Quiz each other on chapter

14

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.
