1

What are the properties of a solution?

-homogenous mixture of two or more substances e.g. Sugar and water
-macroscopic properties do not vary within the sample
-components cannot be separated by filtration, but can be separating by things like boiling
-no components are large enough to scatter visible life

2

The substance that is more plentiful in a solution

Solvent

3

The substance that is less plentiful in a solution

Solute

4

When the solvent has dissolved the maximum amount of solute possible at a certain temperature, and some solid particles remain undissolved

Saturated solutions

5

Saturated solutions are an _______ system where solid particles continually dissolve in the solvent and dissolved particles fall out of solutions

Equilibrium

6

Solutions soluble in all properties, never become saturated

Miscible solutions

7

How can intermolecular forces cause the volume of a solutions to differ from the sum of the volume before mixing?

Strong IMF's can pull molecules together and decrease volume

8

Always infinitely soluble in each other

Gasses

9

Solutions formed by melting, mixing, and solidifying

Solid-solid

10

How does steel differ from iron?

Carbon fills some spaces in iron ions

11

Iron lacks ___________ bonds

Directional

12

In which one elements atoms fill up the spaces of another molecules molecule

Interstitial alloy

13

Alloy where atoms from one element are substituted for others

Substitutional alloy

14

What is the equation for molarity?

M=(moles of solute)/(liters of solutions)

15

Molarity ______ change with temperature

Can

16

Mole fractions __________ change with temperature

Do not

17

What factors affect solubility?

-structure
-temperature
-pressure

18

The mass of solute that dissolves in a saturated solution composed of a specific mass of solvent at a specific temperature

Solubility

19

The solubility of most solids increases as temperature increase, as the process is usually _________________

Endothermic

20

What are the properties of a suspension or mechanical mixture?

-heterogenous mixture of two or ore substances, e.g sand and water
-macroscopic properties are different at different locations within the sample
-in some cases, components can be separated through filtration

21

Identify four properties that change when carbon is added to pure iron in order to steel?

-more rigid metallic bonds
-less malleable
-less docile
-increased density
