Miscible
- when two liquids can dissolved in one
another in all proportions
Immiscible
- when two liquids are mutually
insoluble
4. Effervescence
- the rapid escape of a gas from a
liquid solvent

11. Nature of Solute and
Solvent
Ionic and polar molecules
dissolves in polar solvents;
non-polar solute dissolves in
non-polar solvents.
“Like dissolves like”
Ex. Salt and water
12. Size of Particles
The smaller the particles, the
greater the tendency to
dissolve.
Ex. Pinch of salt and water
13. Temperature
Solids and liquids are more
soluble at higher temperature
but gases are less soluble.
Ex. Powdered milk and hot water
14. Pressure
Solubility of all gases are
increased as the pressure is
increased; solids and liquids
are not affected.
Ex. Water and carbon dioxide
or carbonated drinks
15. Methods of Increasing the
Rate of Solubility
Solids in Liquids
1. PulverizingSolute
2. Agitating Solution
3. Heating the Solvent
