Solubility

Question 1

Mixture

Answer 1

A combination of 2 or more substances

Question 2

Pure substance

Answer 2

Has consistent properties and only one type of particle

Question 3

Heterogenous mixture

Answer 3

Unevely distributed and often visible

Question 4

Homogenous mixture (solutions)

Answer 4

Uniform mixture where every part looks and behave the same

Question 5

Miscible

Answer 5

Liquids that mix completely

Question 6

Immiscible

Answer 6

Liquids that do not mix

Question 7

Soluble

Answer 7

Able to dissolve in a solvent

Question 8

Insoluble

Answer 8

Does not dissolve in a solvent

Question 9

Solvent

Answer 9

Larger amount (water)

Question 10

Solute

Answer 10

Smaller amount (salt)

Question 11

Answer 11

Sand and salt

Question 12

Example of a pure substance

Answer 12

Distilled water

Question 13

Solutions

Answer 13

Made of two or more substances evenly distributed in a single phase

Question 14

Example of immiscible

Answer 14

Oil and water

Question 15

Concentrated solution

Answer 15

Have higher ratio of solute than solvent

Question 16

Description of most solutions

Answer 16

Clear/ transparent with a little color

Question 17

Unsaturated solution

Answer 17

Solution that can still dissolve more solute at a given temperature

Question 18

Why can’t solutions be separated by filtration

Answer 18

Solute particles are too small and evenly mixed

Question 19

Why are solutions considered stable

Answer 19

The Solute does not settle out upon standing

Question 20

Saturated solution

Answer 20

Contains maximum amount of solute that can dissolve at a given temperature

Question 21

Example of supersaturated

Answer 21

rock candy

Question 22

Why are supersatured solutions unstable

Answer 22

The solution crystallizes easily

Question 23

Method to create a supersaturated solution

Answer 23

Heating to dissolve more solute, then slowly cooling

Question 24

What happens in a saturated solution when more solute is added?

Answer 24

Excess solute stays

Question 25

How does electronegativity change across a period (left to right)

Answer 25

It Increases

Question 26

How does electronegativity change down a group (top to bottom)

Answer 26

It decreases

Question 27

Polar covalent

Answer 27

One side strongly attracts electrons while the other doesn’t

Question 28

Noble gases lack electronegativity why?

Answer 28

They do not typically form chemical bonds

Question 29

Polar bond

Answer 29

Bond where electrons are unequally shared, creating partial charges

Question 30

Dipole

Answer 30

Molecule with both positive and negative ends

Question 31

What kind of intermolecular force holds water molecules together

Answer 31

Hydrogen bonding

Question 32

What Property of water is most directly explained by hydrogen bonding

Answer 32

High surface tension

Question 33

Oxygen in a water molecule

Answer 33

Pulls shared electron closer, making it partially negative

Question 34

dissociation

Answer 34

Separation of ions form an ionic crystal when it dissolves in water

Question 35

Electronegativity

Answer 35

The ability of an atom to attract shared electrons in a bond
