A method of separation that employs a system with two phases of matter,a mobile phase and a stationary phase,is called
A)filtration
B)chromatography
C)distillation
D)vaporization
E)homogenization

Question

Quizplus · Accepted Answer

The method described in the question, with a mobile phase (liquid or gas) and a stationary phase, is characteristic of chromatography. In this technique, the sample is introduced into the mobile phase, which carries it through the stationary phase. The components of the sample interact differently with the stationary phase, leading to differences in their retention times and allowing them to be separated. Filtration is a method of separating solids from liquids using a barrier, while distillation separates liquids with different boiling points by evaporating and condensing them. Vaporization refers to the conversion of a substance from liquid or solid form to a gas, while homogenization is a method of mixing two or more substances to create a uniform mixture.
