Inorganic Compounds And Solutions

Front 1

mixture

Back 1

a combination of elements or compounds that are physically blended together but not bound by chemical bonds

Front 2

List three common liquid mixtures.

Back 2

solutions, colloids, suspensions

Front 3

Once mixed together, solutes in a solution remain _____________ ______________ among the sovent molecules.

Back 3

evenly dispersed

Front 4

Because the solute particles in a solution are very small, a solution looks _______________ and _______________.

Back 4

clear, transparent

Front 5

How is a colloid different from a solution?

Back 5

A colloid differs from a solution mainly because of the sie of its particles--large enough to scatter light

Front 6

Colloids usually appear _______________ or ______________.

Back 6

translucent or opaque

Front 7

Is milk a colloid or a solution?

Back 7

milk - both a colloid and a solution - large milk proteins make it a colloid, calcium salts, milk sugar (lactose), ions and other small particles are in solution

Front 8

True or False.
Solutes in solutions and colloids settle out and accumulate on the bottom of the container.

Back 8

False. Solutes do not settle out in solutions and colloids.

Front 9

Suspension

Back 9

the suspended material may mix with the liquid or suspending medium for some time, but eventually it will settle out

Front 10

Name an example of a suspension.

Back 10

blood

Front 11

How is the concentration of a solution expressed?

Back 11

a mass per volume percentage; moles per liter

Front 12

What is the mass per volume percentage?

Back 12

gives the relative mass of a solute found in a given volume of solution

Front 13

What is moles per liter?

Back 13

(mol/L) units which relate to the total number of molecules in a given volume of solution

Front 14

mole

Back 14

the amount of any substance that has a mass in grams equal to the sum of the atomic masses of all its atoms.
