Solids in Solutions:
Dissociation: Is when electrolytes dissolve in water. The molecules within the substance separate, giving it a different structure. During this process, ions form, causing it to conduct electrolytes
Ionization: Occurs when strong acids (6 of them) are place in water and they form ions and so they conduct electricity. This is what catogorizes the strong acids.
Dissolving: Is when non-electrolytes dissolve in a solution. The particles of the substance seperate however their structure remains the same.
Electrolytes:
Electrolytes: Is a substance which conducts electricity when in a solution. This means that ions are present.

Solubility:
Unsaturated Solution: Is when a solution is not saturated meaning more solute can be dissolved into the solution.
Supersaturated Solution: Is when a solution contains more solute than is soluble. This can only occur when other forces are applied. For example, heating a solution may allow for additional solute to dissolve.
Saturated Solution: Is when a solution has the maximum amount of solute that can be dissolved in the solvent while being homogenized at a given temp. When at a given temp, you cannot exceed the saturated solution and any extra solute will be non-homogenized and will be differentiated.
Gases and Solubility: The colder the solvent, the more soluble the gas is. The Higher the pressure, more soluble the gas is.
Temp and solubility: -Solubility of solids increases with temp
-Solubility of liquids is not greatly affected. (takes very high or low temps)
-Solubility of Gases decreases with higher temp (warm pop is less fizzy)
Pressure and Solubility: -Pressure doesn't greatly affect the solubility of solids or liquids.
-Higher pressures increase solubility of gases while lower pressures decreases solubility of gases. (Pressurized can of pop. The fizz remains in liquid much longer)
Solutions Chemistry (L3): Note that in these equations, the solute will always be on top while the solution will always be on the bottom.

Be careful with question involving these formulas. Remember that ml corresponds with g and L corresponds with kg. These are the only questions where you can leave the volume in ml.

Diluted Calculations (L6): Just look at examples and do practice. P.g.12,13
