Solutions
- A solution is a homogenous mixture
- A mixture in which the compound are uniformly intermingled (mixed
really well)
- A mixture in which the compound are uniformly intermingled (mixed
really well)
2 parts of a solution
- Solvent- substance that present in the largest amount
- Solute- substance present in a small amount when compared to a
substance that is present in a large amount
- Water is always the solvent
Ex.
Salt Water
NaCl- solute
Water- Solvent
- Solute- substance present in a small amount when compared to a
substance that is present in a large amount
- Water is always the solvent
Ex.
Salt Water
NaCl- solute
Water- Solvent
Solubility
- Ionic Compound will dissolve in water since ionic compounds are made up of cation(+) and anion(-)
Water
- Water will also dissolve many nonionic compounds
- Polar compound will dissolve in water
- compounds that will contain charges (+ or -)
- Not all things are soluble in water
- Non-polar molecules will not dissolve in to polar solution
- Polar compound will dissolve in water
- compounds that will contain charges (+ or -)
- Not all things are soluble in water
- Non-polar molecules will not dissolve in to polar solution
Electronegativity
- the relative ability of an atom in molecules to attract shared electron to
itself
itself
Solution Concentration
- Every soluble substances will have a limit on how much solute iwll go into the solution
- When this happens, the solution is called saturated
- If you had more solute after the saturation point then it will stay solid
- Unsaturated solution- this type of solution occurs with a solution has not reached the limit of the solute
- When this happens, the solution is called saturated
- If you had more solute after the saturation point then it will stay solid
- Unsaturated solution- this type of solution occurs with a solution has not reached the limit of the solute
Solution Composition
- Qualitative terms
- Concentrated solution
- Dilute solution
- Mass percent (aka weight percent)
Mass percent = (Mass of solute)/(Mass of solution) x 100
- Concentrated solution
- Dilute solution
- Mass percent (aka weight percent)
Mass percent = (Mass of solute)/(Mass of solution) x 100
