Suspensions

Differences between dispersed system and solution

Dipersed system can be translucent = the dispersed particles are so small they can't be seen with naked eye

Types of biphasic systems and their continuous and dispersed phase

What is a surface

Why can water adpot a spherical shape

Force and length of forced applied to the surface = N/m

What is an interface

Why do substances adopt a spherical shape

What is laplace pressure

Work done equation

Detachment method

Capillary rise methods

wWhat is cohesion and adhesion

C = attraction between like molecules

A = different molecules

Balance of these predicts how a dispersed system behaves

When does spreading occur

Consequences of spreading

Happens between 2 immiscible liwquid phases

Film formation

Lens or globule formation

Film formation

Lens or globule formation

When does wetting occur

Contact angles

Advantages of suspensions

How can suspension be administered

Processes before absorption can occur for solutions, susnsions, capsules, tablets

What does the ideal suspension look like

What is settling and stokes' law

Limitations of stokes' law

What is caking

What is flocculation

What are flocculating agents

Sedimentation voume equation

Degree of flocculation equation

How does zeta potential and sedimentation volume change with increasing electrolyte concentration

What is ostwald ripening g
