Total questions: 10
Worksheet time: 8mins
What is a solution?
A means of solving a problem.
A style of painting.
A type of mathematical equation.
A method of cooking food.
How do solutions differ from mixtures?
Mixtures are always homogeneous and do not retain individual properties.
Solutions are homogeneous and consist of dissolved substances, while mixtures can be heterogeneous and retain individual properties.
Solutions do not involve any dissolved substances and are always visible.
Solutions can be heterogeneous and consist of separate components.
What is a characteristic of colloids?
Colloids are always transparent.
Colloids do not scatter light.
Colloids settle at the bottom of a container.
Colloids exhibit the Tyndall effect.
Can you name an example of a colloid?
Sugar solution
Saltwater
Milk
Air
What is one property of suspensions?
Suspensions do not contain any solid particles.
Suspensions are always clear and transparent.
Solid particles in a suspension dissolve completely.
Solid particles in a suspension can settle over time.
How do particles behave in a suspension?
Particles in a suspension are dispersed, can settle over time, and are larger than in a solution.
Particles in a suspension do not settle over time.
Particles in a suspension are smaller than in a solution.
Particles in a suspension are completely dissolved.
What is the main component of a solution?
solute
suspension
emulsion
solvent
What happens to light when it passes through a colloid?
Light is absorbed completely by the colloid.
Light travels straight through without any change.
Light is reflected back entirely by the colloid.
Light is scattered when it passes through a colloid.
How can you separate a suspension?
Crystallization
Evaporation
Filtration, centrifugation, or sedimentation.
Distillation
What is the size range of particles in a colloid?
1 nm to 1 µm
100 µm to 1 mm
10 nm to 100 nm
1 µm to 10 µm
