Why in distillation water evaporates from the condenser?
Water vapors are cooled and condensed in the condenser.
What can water vapour do inside a cold tube in a condenser?
Water vapor condenses in a cold condenser tube.
Why s water circulated in the condenser?
Condensation of gas will reject out heat, running cold water through condenser absorbing heat and help the condensation process.
Why should water in condenser flow uphill during distillation?
Capillary action. When water is in a narrow area or in a porous substance, surface tension pulls the water from areas of high density to areas of low density. Imagine putting a dry sponge in a puddle of water. Like that.
What method can be used to separate pure water from sea water?
There are numerous ways to separate salt from water. The easiest way is by distillation. Boil the saltwater in a pot with a lid slightly offset. As the water runs down the side, collect it in a separate container.
Why in distillation water evaporates from the condenser?
Water vapors are cooled and condensed in the condenser.
3 Why is it important to have a stream of cool water flowing around the condenser during the distillation?
To turn the evaporated product back to liquid. the water must be cold to cool the fumes and cause condensation of fumes passing through the condenser.
Why is the cold waters circulated through condenser from the bottom rather than from the top in the process of distillation?
So that the maximum cooling of the distillate is effected. By sending the cold coolant (usually water) in at the coolest part of the condenser it also reduces thermal shock.
What can water vapour do inside a cold tube in a condenser?
Water vapor condenses in a cold condenser tube.
What are the Sources of error in distillation?
boiling chips are not added to the distillation flask. the thermometer bulb is placed in the boiling liquid. the water to the water-jacketed condenser is not turned on.
Can adding water to salt be reversible?
Yes. A procedure known as distillation would need to be done, i.e., take the solution of water and salt and place in a conical flask attached to a Liebig's Condenser and at the end of the condenser, a beaker. The condenser must be circulated with cold water from below and the hot water removed from top. Heat the solution upto 100 C, and the water will collect in the beaker as 'distillate' while the salt will stick to the sides of the flask.

What is the use of Liebig condenser?
A Liebig condenser is about the most simple condenser going. It has a gas or vapor pathway that is enclosed by a jacket of through which a cooling fluid (water, maybe) is passed. The cooling fluid cools the outer surface of the vapor tube and this cooling effect reaches the inner wall of the vapor tube to cool the vapor and cause it to condense. There are a couple of nice drawings that can be viewed by using the link to our friends at Wikipedia.
Can the water inlet and outlet in distillation be inter converted?
No. Remember: hot air rises & cool air sinks. If the water outlet was to be placed below the condenser, the heat of the water would rise and linger in the condenser, making the condensation process inefficient.
What is an enriching section in a distillation column?
It is the top section of the distillation column. The section where the vapour leaves the column to the condenser.
What are the uses of distillation?
Distillation is used to separate pure water from a thicker liquid substance, such as ink. It does this by heating the water, which then evaporates and rises, leaving the ink. It then travels down a tube, surrounded by a condenser which changes it from water vapor back to water, and then it falls into a beaker at the other end.
Why s water circulated in the condenser?
Condensation of gas will reject out heat, running cold water through condenser absorbing heat and help the condensation process.
What laboratory apparatus used to hold the test tube in distillation?
condenser
