Colloids

Dispersion that pass through ultra filtration & semi permeable membrane

• Molecular Dispersion
• Colloidal Dispersion
• Coarse Dispersion

Dispersion that is detected by electron microscope, pass through filter but not in semi permeable membrane

• Molecular Dispersion
• Colloidal Dispersion
• Coarse Dispersion

Dispersion that cannot pass through filter and semi permeable membrane

• Molecular Dispersion
• Colloidal Dispersion
• Coarse Dispersion

A colloidal system maybe solid, liquid or gas

• True
• False

Attachment of solvent molecules to the molecules of the dispersed phase

• Solvation
• Solubilty
• Solution
• Colloids

system containing colloidal particles that interact to an appreciable extent with the dispersion medium

• Lyophilic Colloids
• Lyophobic Colloids
• Amphiphilic Colloids

system denoting a lack of strong affinity between the dispersed phase and the continuous phase

• Lyophilic Colloids
• Lyophobic Colloids
• Amphiphilic Colloids

They are characterized by having two distinct regions of opposing affinities within the same molecule or ion

• Lyophilic Colloids
• Lyophobic Colloids
• Amphiphilic Colloids

Ultrafiltration is imilar to

• press filtration
• asbestos pad filtration
• filtration using ashless filter paper
• reverse osmosis

Colloidal dispersion which is unstable, irreversible and forms nonspontaneously

• Lyophilic Colloids
• Lyophobic Colloids
• Amphiphilic Colloids
