Mixtures and Solutions - Heterogeneous Mixture

Question 1

suspension

Answer 1

• a heterogeneous mixture which settles on standing and its components can be separated by filtration

Question 2

colloids

Answer 2

• heterogeneous mixtures which do not settle nor are their components filterable
• unlike homogeneous solutions the particles in a colloid are visible and will not pass through a semi-permeable membrane
• consists of two separate phases: dispersed particles (solute) and dispersion medium (solvent)

Question 3

tyndall effect

Answer 3

• unlike solution, collloidal suspensions exhibit light scattering

Question 4

Answer 4

• gas-liquid

Question 5

Question 7

aerosol sprays are colloids. what are the dispersed particles and what is the dispersion medium?

Answer 7

• liquid, gas

Question 8

unlike homogeneous solutions, the particles in a colloid are ______ and ______ through a semi-permeable membrane

Answer 8

• visible, will not pass
