Water & Solubility

Question 0

Polar molecule

Answer 0

Have an uneven distribution of charge due to a greater density of electrons on one end of the molecules.

Question 1

Electronegativity

Answer 1

How attracted the element is to it’s electrons.

Question 2

Hydrogen bonding

Answer 2

Dipole force between a hydrogen atom of one molecule and the oxygen in another molecule.

Question 3

Solution

Answer 3

Formed when one substance is completely dissolved in another.

Question 4

Mixture

Answer 4

More than two substances that haven’t been chemically changed

Question 5

Brownian Motion

Answer 5

The random movement of water molecules.

Question 6

Solute

Answer 6

What is dissolved.

Question 7

Unsaturated

Answer 7

Contains less solute then it can hold at a given temperature

Question 8

solubility

Answer 8

The ability of a substance to dissolve.

Question 9

Van der waals forces

Answer 9

Intermolecular forces that are the week attractive forces that attract molecules of the same substance to each other.

Question 10

Surface tension

Answer 10

The inward force of liquid water molecules have a strong cohesion so they are drawn inward to each other and form a “skin” over the surface water

Question 11

Universal solvent

Answer 11

Water is the universal solvent, it can dissolve substances so readily, that water is almost never found and it’s pure form

Question 12

Supersaturated

Answer 12

Contains more solute then it can hold at a given temperature

Question 13

Dippole-Dippole forces

Answer 13

Polar molecules

Question 14

Solvation

Answer 14

The process of dissolving substances in water.

Question 15

Saturated

Answer 15

Contains the maximum amount of solute for a given amount of solvent at a constant temperature

Question 16

Seed Crystal

Answer 16

Supersaturated solutions are unstable and often will reform crystals if a Seed Crystal is added

Question 17

Surfactant

Answer 17

Can break the hydrogen bond and alter the physical properties of water

Question 18

Dissociation

Answer 18

Compounds become dissociated as in separated into their ions

Question 19

Salinity

Answer 19

A measure of the mass of salts dissolved in seawater

Question 20

Desalination

Answer 20

Process of salts being removed from seawater

Question 21

Aqueous

Answer 21

Water with dissolve substances are called an aqueous solution

Question 22

Capillarity

Answer 22

Rising of liquids

Question 23

Intermolecular force

Answer 23

Can hold together identical particles

Question 24

Adhesion

Answer 24

Describes the force of attraction between molecules that are different

Question 25

Cohesion

Answer 25

Describes the force of attraction between identical molecules

Question 26

Molarity

Answer 26

Is the number of moles of a solute dissolved in 1 L of solution this is also called the molar concentration

Question 27

Solvent

Answer 27

Able to dissolve other substances

Question 28

Hard water

Answer 28

Water that has high mineral content

Question 29

Dilute

Answer 29

Make a liquid thinner or weaker by adding water or another solvent to it

Question 30

Concentration

Answer 30

Present it in a high proportion relative to other substances

Question 31

Insoluble

Answer 31

Incapable of being dissolved

Question 32

Electrolytes

Answer 32

An electrolyte is a substance that ionizes when dissolved in suitable ionizing solvents such as water.

Question 33

Like dissolves like

Answer 33

Like molecules are considered soluble. The term insoluble is given to substances that will only does also having another substance

Question 34

Physical factors that affect solubility

Answer 34

Temperature can increase the rate in the amount of solute dissolved. Pressure increases the amount of gas solute dissolved.

Question 35

Solubility of a solid

Answer 35

Increases as temperature increases

Question 36

Solubility of a gas

Answer 36

Decreases as temperature increases

Question 37

How is water a polar molecule

Answer 37

Because of the V-shaped of the water molecule the two sides become obsolete charged
