Solutions, Suspensions, and Colloids

Solutions Made of very small particles (hard to see even with microscope) Particles will never settle to the bottom of the container Remains uniformly mixed (only see 1 thing) – same color, density Ex: salt water, kool-aid, rubbing alcohol, pop, gasoline

Solutions Solute = substance being dissolved Solvent = substance doing the dissolving Ex: Kool-Aid solute = sugar solvent = water

Solutions

Suspensions Made of large particles A liquid in which visible particles settle to the bottom of the container Ex: muddy water, glacial meltwater, blood

Suspensions

Colloids Medium-sized particles Particles will not settle to the bottom of the container Particles scatter light Ex: milk, gelatin, fog (headlights in fog)

Colloids

Put it all together…. Settle upon standing? Description Solutions Colloids Suspension Settle upon standing? Separate using filter paper? Scatter light?
