Solutions and Suspensions
What is a Solution?
A solution is a mixture in which the constituents are evenly mixed.
solute
solvent
e.g.
sugar + water --> sugar solution
solute + solvent --> solution
Different Types of Solution
State of solvent
State of solute
Example of solutions
Solid Solid Brass
Liquid Solid Sugar solution
Liquid Alcoholic drinks
Gas Fizzy drinks
Gas Gas Air
Water as a Solvent
• Water is a common solvent as many substances dissolve in it
• However, some substances do not dissolve in water e.g. glue and paint.
What is Solubility?
Solubility is the
measure of the amount
of solute that can
dissolve in a
solvent.
Factors that affect solubility
• The nature of the solute
• The nature of the solvent
• Temperature
What is Rate of Dissolving? The rate of dissolving is a measure of
how fast a solute can dissolve completely in a solvent.
Factors that affect Rate of Dissolving
• Temperature• Rate of stirring
• Surface area of solute
Properties of Solutions
• Solute mix completely and evenly in solvent
• Light can pass through
• Filter paper cannot be used to separate solute from solvent
Common examples and uses
Solute Solvent Solution
Soap + Water = Soap water solution
Everyday use:Washing clothes
Common examples and uses
Solute Solvent Solution
Sugar + Water = Sugar syrup
Everyday use:Sweetening tea and coffee
What is a Suspension?
A suspension is formed when a solid does not dissolve in a liquid.
What are Suspensions
Suspensions are mixtures of small insoluble particles in a liquid or gas.
e.g. Flour water is a suspension.
How do we create a Suspension?
Insoluble substance
+ Solvent = Suspension
Sand + Water = Sandy water suspension
Properties of Suspensions
• Suspended particles do not mix completely and evenly
• Light cannot pass through
• Filter paper can be used to separate the suspended particles from the suspension
