Lab 2 PHYSICAL SEPARATION TECHNIQUES Introduction

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 in chemistry.

Filtration

Filtration is any of various mechanical, physical or biological operations that separates solids from fluids (liquids or gases) by adding a medium through which only the fluid can pass.The fluid that passes through is called the filtrate. In physical filters oversize solids in the fluid are retained and in biological filters particulates are trapped and ingested and metabolites are retained
