**Pre-Lab Q 1 = 1-10, Distillation**
Nail polish remover is a common organic solvent mixture used by
every day individuals, and these solvents are responsible for the
strong odor of nail polishes. Nail polish remover is made up
primarily composed of the following organic solvents:
Acetone (bp = 56oC)
CHEM-C343
,Ethyl Acetate (bp = 77oC)
Butyl Acetate (bp = 126oC)
Identify the false statement below regarding this solvent mixture.
A. Butyl acetate has the highest vapor pressure.
B. In order to separate tese three components, you would need to
use fractional distillation.
C. If a bottle of nail polish is opened, acetone is the solvent you
would smell most or first.
D.If a bottle of nail polish remover was left open, butyl acetate
would be the component most likely left in the bottle. -
Answer A. Butyl acetate has the highest vapor pressure.
Match the following terms related to distillation to their correct
definitions.
A. The process by which a liquid is converted into a vapor using
latent (ambient) heat
CHEM-C343
, B. The process where an external heating source is applied until
the vapor pressure equals atmospheric pressure.
C. Small, irregularly shaped pieces of material (often made
from such as alumina, calcium carbonate, porcelain or carbon)
added to liquids to make them boil more smoothly.
D. The pressure exerted by a vapor in thermodynamic
equilibrium with its condensed phases (solid or liquid) at a given
temperature.
E. Chemical additive that reduces and hinders the formation of
foam in liquids.
F. One cycle of evaporation and condensation in a distillation. -
Answer A. Evaporation
B. Boiling
C. Boiling chip
D.Vapor Pressure
E. Anti-foaming agent
