Obtain approval from your laboratory instructor before starting a distillation. Make certain the apparatus has an opening...Use a fresh boiling chip each time a liquid is boiled to avoid bumping... Do not heat any distillation pot to dryness. Do not heat a closed apparatus because abrupt release of the increased pressure may propel reagents or pieces of glass... Also glassware that is superheated could crack. Before heating a flask, clamp the neck of the flask to support it in an elevated position to allow withdrawal of the heat source and rapid cooling... page 3-4.

What is distillation and purification?
Purification is when a liquid goes through a process for it to become more cleaner. Distillation is when a liquid is not sparkling and when chemicals are not added.
What is distillation and evaporation are methods to?
Distillation is a method of separation for liquids.Evaporation is a physical change, from liquid to gas.
What is the negative impact of liquid hold up in distillation?
When liquid holdup occurs, the repeated boiling and condensation on which the separation depends is interrupted and distillation becomes less efficient.
The process that can separate two substances in a mixture by evaporating a liquid and recondensing its vapor?
The process you describe is known as distillation.
Why distillation cannot be done with volatile solids dissolved in liquids?
The volatile solids will have a vapor pressure at the boiling point of the liquid which means some of that solid will vaporize and go thru the distillation process with the liquid. When condensed you will not get a pure liquid.
Is the separation of an organic liquid by distillation better or worse if salt is present?
This is not important if the salt is not soluble in a component.
How can you overcome the problem of decomposition of certain organic liquid during distillation process?
you can over come the problem of decomposition of certain organic liquid by rarefaction atmospheric pressure that the boiling point of liquid become less than of its previous that prevent decompose it before its boiling.
Why should organic liquids in general not distilled to dryness?
Organic liquids are usually highly flammable. Distillation of a substance involves heating it, and the heat needed to drive off all water from an organic liquid will likely resultin a fire.
Which liquid would be the first to be collected in the fractional distillation?
fractional distillation this is a liquid with the lowest boiling point
What is a liquid-liquid solution that can be separated by distillation?
A liquid-liquid solution that can be separated by distillation would be alcohol and water. Water will boil at a higher temperature allowing separation.
In distillation a liquid and then condenses?
correct! distillation is the prosses of evaporating a liquid to purify it then recondence it back to a liquid. This prosses can be used for removing salt from water.
Is there two changes of state in distillation?
The changes of state that happen during distillation are: Liquid to a gas and gas to a liquid
How fractional distillation is used?
Fractional distillation is used to separe the components of a liquid.
How do you separate a liquid dissolved in a liquid?
The separation is made by distillation.
What is distillation and purification?
Purification is when a liquid goes through a process for it to become more cleaner. Distillation is when a liquid is not sparkling and when chemicals are not added.
What is theory on distillation?
Distillation is based on the differences between boiling points of the components of a liquid.
How can prepare nitrogen liquid?
The liquid nitrogen is prepared by fractional distillation of liquid air.
