Dispersive Liquids

Objectives

• Explain the difference between solutions, suspension and colloidal dispersions at the structural level
• Describe the categories of colloids that exist between the three main states of matter
• Distinguish between colloidal dispersions, other types of solid-liquid mixture and other colloids
• Investigate how concentration affects the formation of a colloid
