2. Factors
Affecting
Solubility

3. Unlocking of Word
Difficulties
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
Effervesces
- the excess carbon dioxide rapidly
bubbles out of solution
Nature
- kind

6. TABULATION of RESULTS
Materials Miscibility in Oil
Tap water Immiscible
Kerosene Miscible
Alcohol Miscible

7. Materials Hot water Cold Water
Rock Salt Fast Slow

8. Materials Solubility In Water
Iodized Salt Dissolved fast
Rock Salt Dissolved slowly

9. Materials Observations
Shaked Carbonated Drink Effervesces produce or the
excess carbon dioxide rapidly
bubbles out of solution
Undisturbed Carbonated Drink Fizz sound produce and
effervescence produced or
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

17. If you are the parent of the boys in the
film of Muro-ami, would you allow
your child to be one of the divers?
Why? Why not?
