TYPES OF SOLUTIONS AND ENERGY OF SOLUTION Flashcards
mixture of two or more substances evenly distributed throughout a single phase
Solutions
are thoroughly mixed in a solution such that each part of a mixture has uniform composition and properties
Atoms, Ions, and Molecules
the substance dissolved in a solution as is usually present in smaller amount
Solute
is the dissolving medium
Solvent
The components of solution may be ?
solid, liquid or gas
SOLID SOLUTION
SOLUTE SOLVENT Examples?
1. SOLID SOLID
2. LIQUID SOLID
- Copper dissolved in in gold (alloys)
- Mercury with sodium (amalgam)
LIQUID SOLUTION
SOLUTE SOLVENT EXAMPLES?
1. SOLID LIQUID
2. LIQUID LIQUID
3. GAS LIQUID
- SODIUM CHLORIDE DISSLOVED IN WATER
- ETHYL ALCOHOL DISSOLVED IN WATER
- CARBON DIOXIDE DISSOLVED IN WATER (SODA WATER)
GASEUOS SOLUTION
SOLUTE SOLVENT
1. LIQUID GAS
2. GAS GAS
- WATER VAPOUR IN AIR (CLOUD)
- MIXTURE OF HELIUM - OXYGEN GASES
Contains less solute than the solvent’s capacity to dissolve. This means that the solution can still dissolve more solute
Unsaturated Solution
contains the maximum amount of solute that the solvent can dissolve at a certain temperature
Saturated Solution
Contains more dissolved solute that in present in saturated solution. This solution is unstable such that the excess solute can crystallize in the solution by adding a “seed crystal”
Supersaturated Solution
For two substances to form a solution, they must have the ______ nature in terms of _______
For two substances to form a solution, they must have the SAME nature in terms of POLARITY
The formation of a liquid solution takes place in ____ steps
Three steps
- Overcoming the IMF in the solvent to give room for the solute. Termed as ?
“expanding the solvent”
- ______ the solute into its individual component. Termed as “expanding the ________.
- Separating the solute into its individual component. Termed as “expanding the SOLUTE”
