Investigate properties of saturated and unsaturated solutions.
Saturated and Unsaturated Solution
Have you ever experienced that upon mixing sugar to a glass of water, it no longer dissolved? What does undissolved particles at the bottom of the glass tells us?
Solution is a homogenous type of mixture; components are evenly distributed.
Solute is present in lesser amount; substance that is being dissolved.
Solvent is present in greater amount; substance that dissolves the solute.
Solubility is the characteristic of a substance to be dissolved.
Soluble substances can be dissolved in a solvent.
Insoluble substances cannot be dissolved in a solvent.
Ways to increase the Dissolution Rate
Decrease the particle size
By increasing decreasing the particle size, the surface area of solute in contact with the solvent is increased
Example: Using powdered sugar instead of sugar cubes
Increase the temperature
The hotter the solvent is, the faster the solute dissolves.
Example: using lukewarm water in dissolving the jelly powder, instead of cold water
Increase mixing or stirring rate
Rapid stirring increases the collision of particles, thereby increasing its dissolution.
SATURATED SOLUTION
SATURATED SOLUTION
A solution that contains the maximum amount of solute it can hold (that if you add more solute, it no longer dissolves)
UNSATURATED SOLUTION
UNSATURATED SOLUTION
A solution that contains less than the maximum amount of solute that is capable of being dissolved.
