Fractional distillation is the process used to separate a mixture of miscible liquids whose boiling points differ by less than 25 o C. The experimental setup is similar to that of distillation except for a …

Acetic acid is treated with Ca(OH)2 and the product so obtained is subjected to distillation. The final product is : propanal propanone ethanal ethanol

Assertion :While separating a mixture of ortho- and paranitrophenols by steam distillation, name the isomer which will be steam volatile. Reason: o-nitrophenol is steam volatile due to chelation …

Assertion :Glycerol is purified by distillation under reduced pressure. Reason: Method of distillation under reduced pressure is used to purify liquids having very high boiling points and those, which …

In simple distillation, the apparatus consists of a distillation flask connected to a condenser. On the other hand, the apparatus used for fractional distillation is similar to that of simple distillation, but an …

These are generally insoluble in water at room temperature but are miscible with water vapour in the vapour phase. A suitable method for the extraction of these oil from the flower is: crystallisation …

Glycerol (B.P. 290°C) is separated from spent lye in the soap industry by distillation under reduced pressure, as for simple distillation very high temperature is required which might decompose the …

In order for simple distillation to work, the two liquids' boiling points must have a difference of at least 25 degrees Celsius. Simple distillation is used when the difference in boiling points is more than 250C.

Reason Ortho isomer associates through intermolecular hydrogen bonding while Para isomer associates through intramolecular hydrogen bonding. Assertion Ortho and para-nitrophenols can be separated …

A Explain why an organic liquid vaporizes at a temperature below its boiling point in its steam distillation. (Text Book Q.No. 9) In steam distillation, the organic liquid starts to boil when the sum of vapour …
