how will you separate a mixture of carbon tetrachlorode and water? explain the principle of the method?

Answer 1

Carbon tetra chloride and water are two immiscible liquids, therefore will form two distinct layers in a container.Water being lighter will occupy the top part. The two can be separated by a separating funnel.
Here the principle of separation is immiscibility and difference in densities.
Another better method of separation can be distillation.The boiling point of carbon tetra chloride being lesser it will get evaporated first at 76.7 deg.C,which can be collected in a container.The liquid remaining behind will be water only.

Answer 2

hey ,
i did this experiment for my project...
dont worry
stick to basics...

i will start from the basics........

I agree separating funnel is a better method

but the last option is....

Carbon tetrachloride boils at 76C and water at 100C. They should be separable by simple distillation.

The carbon tetrachloride will be saturated with water........

You may not see it but water will be dissolved in the organic phase......... Leave the distilled carbon tetrachloride standing over finely divided anhydrous sodium sulfate for a day should dry it up fairly effeciently and give you an almost anhydrous product.

You should realize that carbon tet is a liver toxin and that this procedure should be performed in an efficient hood.

Carbon tetrachloride will little be dissolved in the water.Decanting from water then drying it with anhydrous calcium chloride will be ok.

hope this helps its the best answer..........
all the best,,,,,,,,,,,,,,,

Answer 3

Chloroform is only very slightly soluble in water, but when you distill a mixture of water & chloroform you will get an azeotrope with ~97% chloroform and ~3% water so distillation really isn't buying you anything here, decant or use a separatory funnel. After separation, there will be little chloroform in the water you could get rid of it by bubbling air through it (sparging). Or, possibly by passing it through a bed of activated charcoal. There will also be a little water in the chloroform, you could get rid of it by using a drying agent such as activated 3A molecular sieves, or anhydrous sodium sulfate.

Answer 4

Take glass separating funnel, add mixture of CCl4 and water, as CCl4 is water insoluble and heavier than water , the seperated two lyear consists of lower layer of CCl4 and upper layer of water. You can comfortably can separate this mixture.
