HW 18/CH 16
How can the components of a mixture be separated from one another?
Components of a mixture can be separated by physical means. One method is filtration, another is distillation.
HW 18 CH 16 RQ 3
How does distillation separate the components of a mixture?
Distillation separates the components by using the different boiling points or components. The component that boils at a lower temperature is vaporized and is collected by exposing it to cooler temperatures over a receiving flask which collects the condensed purified liquid.
HW 18 CH 16 RQ5
How is a solution different from a suspension?
A solution is a homogeneous mixture in which all components are in the same phase. A suspension is a homogeneous mixture in which the various components are in different phases.
