Solubility

2. Solution Type of homogeneous mixture
Cannot differentiate between solute and solvent
Solute: substance that dissolves in another
Solvent: substance capable of dissolving a solute

3. Solutions Outside of Body
Examples of Solutions
Solutions Outside of Body
Solute (s)
Solvent
Solutions Inside the Body

4. Concentration
Quantity of solute (mass) dissolved in a certain quantity of solvent (volume)
Symbol = C
Equation
Concentration = mass / volume
C = m/V
Units = grams per litre (g/L)

5. Sample Concentration Problem
A 355 mL can of Sprite has 40 g of sugar
in it. What is the concentration of sugar in
that soda?

6. + water = Juice Dilution
Method used to decrease the concentration of solute in a solution by adding solvent.
Concentrate
+ water = Juice
(diluted concentrate)

7. Dilution Equation Since mass of solute remains the same: C V = C V
Where:
C  initial concentration (g/L)
V  initial volume (L)
C  final concentration (g/L)
V  final volume (L) 1 1 2 2 1 1 2 2

8. Sample Dilution Problem
You are preparing lemonade. The concentration of
sugar is 50 g/L. You taste it and realize this is way too
sweet. You decide to add 750 mL of water. What is
the new concentration of sugar in your lemonade?

9. Solubility Maximum concentration Characteristic property Examples:
Chlorine in water = 7.3 g/L
Oxygen in water = 0.04 g/L
Glucose in water = 1000 g/L

10. Types of solutions Unsaturated – can still add solute to solvent
Saturated – max amount of solute contained in solvent
Supersaturated – because temperature is , more solute than usual contained in solvent
