3 physical methods in separating the components of a homogeneous mixture
DISTILLATION, ADSORPTION, EXTRACTION
method use in separating naphthalene vapor from sodium chloride, methylene blue
Sublimation
Method used in recovering naphthalene vapor to naphthalene crystals
Deposition
Methods used in separating methylene blue from sodium chloride
Adsorption by activated carbon and filtration
Method used in separating sodium chloride and water
Distillation
Method used in separating sodium chloride and water
Distillation
Chloroform and water do not mix with each other (immiscible), thus forming 2 layers. What do you call the lower portion in the test tube?
Chloroform layer
Chloroform and water do not mix with each other (immiscible), thus forming 2 layers. What do you call the upper portion in the test tube?
Aqueous layer
the transition of a substance directly from a solid state to a gas state without passing through the intermediate liquid phase
Sublimation
the process of separation of liquid from solid and other immiscible (non-mixing) liquids, by removing the liquid layer at the top from the layer of solid or liquid below.
Decantation
process involving the conversion of a liquid into vapour that is subsequently condensed back to liquid form.
Distillation
the process in which solid particles in a liquid or gaseous fluid are removed by the use of a filter medium that permits the fluid to pass through but retains the solid particles.
Filtration
the sticking of a particle to a surface. The particle can be a gas, liquid, or solid atom, molecule, or ion,
Adsorption
a method to separate compounds based on their relative solubilities in two different immiscible liquids
Extraction
