Pure substances and Mixtures
Describes a substance that will dissolve in a liquid.
What is soluble?
A method of separating an insoluble solid from a liquid
What is Filtration?
A mixture of salt and sand needs to be separated. What technique(s) would be used?
Filtration and Evaporation/Crystallization
This equipment is used to measure the temperature of the vapor produced in distillation
What is a thermometer?
Is made of 2 or more materials physically combined; can be separated
Describes when liquids aren't able to mix.
What is immiscible/immiscibility?
A separation technique that uses evaporation to separate the parts of a solution. The solvent evaporates and leaves behind the solute as crystals.
What is crystallisation?
What technique is used to separate miscible liquids with similar boiling points?
What is fractional distillation?
This serves as a sieve to catch sediments that are too big to pass through
What is filter paper
A heterogeneous mixture that is unable to be filtered
What is a colloid?
Describes the solids left behind in the filtration paper after the mixture has been poured in.
What is residue?
Separating a mixture based on their difference in density and immiscibility?
What is a separatory funnel?
This separation is dependent on solubility and particle size
What is filtration?
Assists in safer boiling
What are anti-bumping granules?
Has a different appearance and composition throughout. Non-uniform
What is a heterogenous mixture?
A mixture of a gas or liquid and an insoluble substance. The insoluble substance settles to the bottom when the mixture is left to stand.
What is a suspension?
A mixture of a dissolved solid in a liquid is heated so that the liquid evaporates. They have very different boiling points. The vapour is collected and condenses into a liquid.
What is simple distillation?
This equipment has a large surface area inside that allows for the condensing of less volatile liquids
What is a fracionating/fractional column?
This has an inner chamber that allows liquids to condense and be collected in a receiver flask.
What is a Liebig Condenser?
Has the same appearance and composition throughout. Uniform
What is a Homogenous mixture?
The point where two immiscible liquids meet
What is the liquid interface?
process of separating out parts of chemical mixtures (usually colours) dissolving them onto an absorbent material (usually paper)
What is chromatography?
Sugar burns easily. James wants to separate sugar from water. What would be the best technique(s) to use?
Crystallization
This is used to separate liquids with different densities.
What is a separatory funnel?
