Question

Dstilaion is when material is heated to melting and then separated. a) Distillation is c) Distillation is when a substance is dissolved, heated, and then precipitated. What is the singular most potentially dangerous aspect of distillation? a liquid is evaporated and then re-condensed in another container. 2. a) the reduced pressure required for the procedure the exothermic nature of the reaction b) c) the use of flammable materials in the presence of heat , liquid will boil When the vapor pressure of a liquid equals the a) melting point 3. b) internal pressure c) boiling point d) external pressure 4. Simple distillation is generally only recommended for purifying compounds with a large difference in boiling point. In fact, a good rule of thumb is that simple distillation is only effective at separating compounds if the difference between their boiling points is 60°C or more. With that in mind, would you expect simple distillation you did to effectively separate the compounds used in this lab? a. A good place to look up physical properties of organic solvents is the American Chemical Society's Division of Organic Chemistry website (https://www.organicdivision.org/orig/organic solvents.html) Use this site to find and record the boiling points of .. b. BPCO Compound Tetrabydrofuran (THF) Diglyme (diethylene glycol dimethyl ether). c. Could simple distillation be used to effectively separate a mixture of THF and diglyme? of temperature during the simple distillation of an organie solvent.

Explanation / Answer

1. (b) Distillation is separation of two liquids based on their relative volatility.

2. (c) Use of flammable materials to reach the boiling temperature of liquids.

3. (d) When the vapor pressure of liquid equals the internal pressure, it will boil.
