What will this mixture look like? Can you think of three different appearances?Slide2
Colloid
Suspension
SolutionSlide3
When one thing dissolves in another, it is called a solution.If the solvent is water, it is called an
aqueous solution
.
Solute
(the solid)
Solvent
(the water)Slide4
If it dissolves = soluble.If it does not dissolve = insoluble.
Soluble and InsolubleSlide5

Which of the following do you think is concentrated, diluted or saturated?A Matter of ConcentrationSlide8
Concentrated = more solute is added to the solvent.Diluted = less solute is added to the solvent.
Saturated
= no more solute can dissolve in the solvent.Slide9
