Solutions
Give an example of a solution
What is the name for a liquid in which another substance dissolves?
Solvent
Name two pieces of equipment needed in the process of filtration.
Filter paper, funnel
What sorts solids based on their particle size?
Sieving
Identify the three states of matter
Solid, liquid, gas
Define the term 'soluble'
Able to be dissolved
What is the name for a substance that dissolves in a liquid?
Solute
The filtrate is the...
Substances that pass through the filter
What is the name of the separation technique used by gold panners?
Gravity separation
What must be added to turn a solid into a gas?
Energy (heat)
Define the term 'insoluble'
Not able to dissolve
A dilute solution has... (solute/solvent)
A large amount of
A small amount of
A large amount of solvent
A small amount of solute
The residue is the...
Substances that get trapped by the filter
Suggest a technique for separating salt from salt water.
Boiling & evaporation
Describe the movement of particles in a gas.
Refer to the spaces between particles, their kinetic energy (movement), and their behaviour in a sealed container.
Large spaces between particles, a lot of kinetic energy (flying around rapidly and colliding), particles will fill the whole container.
Is salt water a solution or a mixture?
Solution
A concentrated solution has... (solute/solvent)
A large amount of
A small amount of
A large amount of solute
A small amount of solvent
True or False
Filtration can be used to separate the components of a solution.
False.
Filtration can only be used to separate an insoluble substance from a liquid.
Describe how solubility is important in chromatography.
Chromatography separates substances based on solubility. The higher the solubility the faster the substance will move along the column.
Describe the movement of particles in a solid.
Refer to the spaces between particles, their kinetic energy (movement), and their behaviour in a sealed container.
No spaces between particles, small vibrations, will stay in a fixed position within a container and will not fill the space.
Is sand in water a solution or a mixture?
Mixture
A solution is said to be ________________ when no more solute will dissolve in it.
Saturated
Describe how particle size is important in filtration.
Particle size of the reside must be larger than the holes/pores in the filter.
Describe how boiling points are important in distillation.
The substance with the lowest boiling point will turn into a gas first, leaving substances with a higher boiling point behind.
What is the name given to the process of turning a solid into a gas, and then a gas into a solid?
Sublimation
Deposition
