What is steam distillation and why is it a preferred technique to purify high boiling liquids that are water insoluble?
steam distillation is an effective way to separate slightly volatile water insolube substance from nonvolatile material
What else can I help you with?
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 separation technique would most likely be used if a solvent we saved?
If a solvent were to be saved, distillation would be the separation technique of choice. Distillation involves heating the mixture to separate components based on their different boiling points, allowing the solvent to be collected and reused.
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 reverse evaporation?
Reverse evaporation is a process used in distillation where a lower boiling point liquid is evaporated first, leaving behind a higher boiling point liquid in the distillation flask. This technique is often used to separate components with close boiling points or when the higher boiling point liquid is the desired product.
How to find the boiling point of a compound"?
To find the boiling point of a compound, you can consult a reference book or online database that lists the boiling points of various compounds. Alternatively, you can use a laboratory technique called distillation to determine the boiling point experimentally.
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.

How do you decide what steps to take before separating a mixture?
To separate a mixture, first identify the physical properties of the components, such as boiling point or solubility. Then, choose a suitable separation technique based on these properties, such as distillation for volatile components or filtration for insoluble solids. Finally, apply the chosen technique sequentially to isolate the components effectively.

Why steam distillation is preferred over the fractional distillation?
Steam distillation is preferred over fractional distillation in cases where the compounds are heat sensitive and may decompose at high temperatures. Steam distillation also allows for the separation of compounds that are immiscible or have different boiling points that are very close together. Additionally, steam distillation is often a more efficient and cost-effective method for isolating volatile compounds from natural products.
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 is reverse evaporation?
Reverse evaporation is a process used in distillation where a lower boiling point liquid is evaporated first, leaving behind a higher boiling point liquid in the distillation flask. This technique is often used to separate components with close boiling points or when the higher boiling point liquid is the desired product.
What is FEV distillation?
FEV distillation, or fractional distillation in a vacuum, is a method used to separate substances with close boiling points. By lowering the pressure in the distillation apparatus, the boiling points of the components are also lowered, allowing for more efficient separation. This technique is often used in industries such as oil refining and chemical processing.
When would distillation be used instead of crystallisation?
Depend on liquid property, if it had similar boiling point but different freezing point then it might consider crystallisation and distillation when the boiling is easier to separate them. If the liquid is easily thermally decompose then it might need to consider crystallisation. there is no definite answer to this question. Very depending on what chemical working with.
What does distillation?
Distillation is the separation of two substances by boiling.
