Question

How can we seperate a mixture of two immiscrible liquids; describe with a neat diagram the method of sublimation?​

Answer 1

Answer:

Mixtures of liquids can be separated according to their properties. The technique used depends on whether the liquids dissolve in each other, and so are miscible, or if they are immiscible. Fractional distillation is a technique used to separate liquids according to their boiling points. Chromatography is used to separate mixtures of coloured compounds.

Separation of liquids

Liquids can be described in two ways – immiscible and miscible. The separation technique used for each liquid depends on the properties of the liquids.

Immiscible liquids



Oil and water can be separated using a funnel

Immiscible means that the liquids don't dissolve in each other – oil and water are an example. It is possible to shake up the liquids and get them to mix but they soon separate. Separating immiscible liquids is done simply using a separating funnel. The two liquids are put into the funnel and are left for a short time to settle out and form two layers. The tap of the funnel is opened and the bottom liquid is allowed to run. The two liquids are now separate.
