When to liquids in a mixture have different boiling points they can be separated by?
Two liquids in a mixture with different boiling points can be separated by distillation.
What is the process that separates a mixture based on the boiling points?
That's "fractional distillation" or in the world of oil, "fracking."
What separation technique involves using different boiling points?
Distillation. By applying heat to the mixture it will boil, but the different liquids within the mixture will boil or vapourise at different temperatures. This means that the different vapours can be drawn off at different stages and then condensed back into liquid form. One example of where this is used on an industrial scale is at a oil refinery. The crude oil extracted from oil fields is heated in large distillation towers. These then separate out different products from heavy oil (higher boiling point), through to petrol (medium boiling point) to propane (low boiling point).
What is the technique used to separate ethanol from a mixture of ethanol and propanol?
Distillation would work. Those two liquids have different boiling points, and heating it up to the boiling point of the lowest liquid would cause it to boil away, leaving behind the other.
What is the difference between boiling and distillation?
Both start by boiling a liquid, but in distillation the vapor produced by boiling is captured, cooled, and condensed back to a liquid.
Why is ditillation used as a separating technique?
Distillation is a useful separating technique because every compound has a unique boiling point. Distillation takes advantage of a compound's boiling point to separate it from other compounds.
When to liquids in a mixture have different boiling points they can be separated by?
Two liquids in a mixture with different boiling points can be separated by distillation.
Explain fractional distillation and how it is used in refining oil?
Fractional distillation is a technique used to separate liquids with different boiling points. It is used in refining oil, whereby different types of oils are separated according to their different boiling points.
What does distillation?
Distillation is the separation of two substances by boiling.

What is the effect of an insoluble solid such as glass on the boiling temperature of a liquid?
If the solid is insoluble, it will have little or no effect on the boiling point. If it is soluble, it will raise the boiling point.
Why is fractional distillation is an appropriate technique to separate ethanol and water?
alcohol and water have different boiling point. i.e bp of alcohol is78C andwater is100C
What is purifying by boiling and condensation?
distillation
What is seperating mixtures by their boiling points?
Distillation, or sometimes called fractional distillation.
