Ch. 20 - Mixtures and Solutions

Which of the following is NOT a characteristic of mixtures?

• physically separable

• chemically separable

• chemically combined

• variably composed

one unbroken phase in which the other phases are mixed

• Continuous Phase of Mixture

• Dispersion Phase of Mixture

the phase that is suspended throughout the mixture

• Continuous Phase of Mixture

• Dispersion Phase of Mixture

Gels, sols, emulsions, foams, aerosols, and alloys are all types of _______ mixtures.

• Heterogeneous

• Homogeneous

two phase mixtures; solid dispersed in a liquid; Example: dessert gelatin (jello)

• Foams

• Aerosols

• Gels

• Sols

• Alloys

• Foams

• Aerosols

• Gels

• Sols

• Alloys

solid-in-liquid mixture that is more like a liquid; often thickExample: paints and inks

• Foams

• Aerosols

• Gels

• Sols

• Alloys

contain two or more distinct liquid phases; they are immiscible; Each dispersed phase will usually separate from the continuous phases over time toform a layer.Example: milk, mayonnaise, butter

• Foams

• Aerosols

• Gels

• Emulsions

• Alloys

gas whipped into a liquid (gas-in-liquid)Example: whipped cream and shavingcream

• Foams

• Aerosols

• Gels

• Emulsions

• Alloys

solid particles or liquid drops dispersed in a gas (solid-in-gas or liquid-in-gas)Example: hairsprays and air fresheners

• Foams

• Aerosols

• Gels

• Emulsions

• Alloys
