Physical Separation

Lab #2. PHYSICAL SEPARATION TECHNIQUES. Introduction. When two or more substances, that do not react chemically, are blended together, the result is a mixture in which each component retains its individual identity and properties. The separation of the components of a mixture is a problem frequently encountered.
