Solution |
A homogenous mixture of a solute dsitributed through a solvent |
|
|
Aqueous Solutions |
Solution where water is the solvent |
|
|
Miscible/immiscible |
Miscible: water+alcohol, gasoline Im: oil and water |
|
|
Solubility |
Extent to which a solute dissolves a solvent. Gases: temp +, solubility - S & L: temp +, solubility - |
|
|
Effects of solubility |
Temperature: increasing the temperature as youre mixing breaks down the particles. Pressure: only gases Nature of Solute/solvent |
|
|
3 things for something to dissolve and the energy associated with it |
1) end: energy to break up a solute into ions and components 2) end: the energy to make room in a solvent for a solute 3) ex: the interaction of a solute and a solvent to form a solution |
|
|
Solution from a solution |
McVc=MdVd Add (ml) of (Mc) (name of solution) to enough water to form (Vd) of (Md) (name of solution) |
|
|
Standard Solution |
A solution whose exact concentration is known because you prepared it. 1L=(M which is mol) Weighout (answer g) of (solution) and add to enough water to form (L) of a (M) (name of solution) solution |
|
|
Electrolyte |
Any compound that can form ions when it dissolves in water and haz ability to conduct an electrical current. Ex: Potassium, Sodium, Cl-, HCO3- |
|
|
Non-electrolyte |
Molecules and atoms. Dont conduct electricity. |
|
|
Weak Electrolyte |
Small number of ions in solution |
|
|
Strong Electrolyte |
Large number of ions in solution |
|
|
Dilute |
Lot of solvent, small amount of solute |
|
|
Concentrate |
Large amount of solute, small amount of solvent |
|
|
Unsaturated |
Less than equilibrium amount of solute. Can add more |
|
|
Saturated |
Equilibrium of the amount of solute in the solution |
|
|
Supersaturated |
More than the equilibrium amount of solute in the solution |
|
|
Colligative Properties |
Solution properties that depends primarily on the concentration of solute particles and not the identity. 1) Boiling Point Elevation: add solute the bo goes up 2) Freezing Point Decreases 3) Vapor Pressure Lowering: bp goes up once salt added, less gas, less vp, less pressure on gas 4) Osmotic Pressure |
