15.3: Heterogeneous Aqueous Systems

......................................................is a mixture from which particles settle out upon standing.

• A suspension

• A colloid

• A solution

A suspension differs from a solution because the particles of a suspension are much ............................... and do not stay suspended indefinitely.

• smaller

• larger

The particles in a typical suspension have an average diameter .............................................

• 1 nm

• less than 1000 nm

• greater than 1000 nm

Suspensions are .......................................because at least two substances can be clearly identified.

• homogeneous

• heterogeneous

................................................is a heterogeneous mixture containing particles that range in size from 1 nm to 1000 nm which are spread or dispersed, throughout the dispersion medium

• A suspension

• A colloid

• A solution

Colloids have particles ...................................... those in suspensions and ..................................... those in solutions.

• smaller than / larger than

• smaller than / smaller than

• larger than / larger than

The scattering of visible light by colloidal particles is called the ......................................

• Newton effect

• Tyndall effect

• Avogadro's effect

Do not exhibit the Tyndall effect.

• A suspension

• A colloid

• A solution

...................................means to adhere to a surface

• Adsorption

• Absorption

• Condensation

All the colloidal particles in a particular colloidal system will have........................ charge, although the colloidal system is neutral.

• different

• the same
