1. Solubility

2. Review Concentration
If the concentration of sugar in water is determined to be 0.45 g/ml and 100 g of sugar was used to make the solution how much water was used?

3. Review Concentration
What is the concentration in ppm of mg/L?

4. Review Concentration
What is the concentration in mg/L of 12.9 ppm?

5. Saturated and Unsaturated Solutions
Mix and Flow of Matter
Saturated and Unsaturated Solutions
The limit to concentration is called solubility.
(The maximum amount of solute that can be dissolved in a fixed volume of solvent at a given temperature.)
a saturated solution is one in which no more solute will dissolve in a specific amount of solvent at a specific temperature
( Using the particle theory, the attractive forces between the particles becomes balanced and no more particles of the solute can be attracted by the particles of the solvent )

Saturated and Unsaturated Solutions
an unsaturated solution is one in which more solute can be dissolved in a specific solvent at the same specific temperature

Supersaturated Solutions
(Solubility is a unique property – See Solubility Chart
a solution that contains more solute than would normally dissolve at a certain temperature is called a super-saturated solution.

9. Quantitative analysis of solutions
Saturated – how much solute can the solution hold?

10. Factors Affecting Solubility
Mix and Flow of Matter
Factors Affecting Solubility
Water - is called the 'universal solvent', because it can dissolve so many materials.
Solvents can dissolve solutes if they have the same polarity

11. Solubility Polarity – define
Dissolving demo ie. oil and vaseline, sap, or water and sugar, vinegar
Soap and hydrophillic and hydrophobic emulsification

12. What causes the dissolving?
Dissolving occurs because the attraction between particles is strong
There is a stronger attraction to another particle than there is to the particles of the same substance

13. Solubility Changes With Temperature
Mix and Flow of Matter
Solubility Changes With Temperature
Solubility increases as the temperature of the solvent increases, because more space is provided between the particles for the solute particles to fit (dissolve) into.
The reverse is true for a gas though - as the temperature increases, the solubility of a gas, in a liquid solvent decreases.
