Chapter 1_Solubility Vocabulary

Question 1

Solvent

Answer 1

The substance that does the dissolving in a solution (EX: water). Water is the universal solvent since it can dissolve many substances.

Question 2

Chemical Properties

Question 3

Mixture

Question 4

Atoms

Answer 4

The smallest particle of an element that has the chemical properties of that element.

The building blocks of mater.

Made up of Protons (+), Electrons (-) and Neutrons (0)

Question 5

Solute

Answer 5

The substance that is dissolved in a solution (EX: Kool-aid mix)

Question 6

Pure Substance

Question 7

Compound

Answer 7

A molecule that has two or more different elements bonded together.

Example: H and O = H₂O

Question 8

Colloid

Answer 8

Partlicles are larger than in a solution but do not settle out.

Have the characteristics of both suspensions and solutions but the suspended particles are big enough to be viable but are small enough not to settle out.

Example: Fog, Jello

Question 9

Homogeneous

Answer 9

Uniform Distribution.

Composition of the mixture is the same throughout. Difficult to separated substances.

Example: Sugar in Water, milk, soft drink, blood

Question 10

Heterogeneous

Answer 10

Parts do not combine completely or evenly.

Composition is not uniform throughout. Can separate substances relatively easily.

Example: Sand and Water, Lemon juice and Tea,
Iron shavings in sand.

Question 11

Physical Properties

Question 12

Solution

Answer 12

Group of molecules that are mixed in a completely even distribution.

A type of homogeneous mixture formed when one substance dissolves in another. “Best mixed” of all mixtures

“A Solute is dissolved in a Solvent”

Example: KoolAid mixed with Water

Question 13

Suspension

Answer 13

Can see the particles with the naked eye and they will settle out over time.

Other words similar to solution except that the particles suspended will settle out over time.

Example: Vinegar and oil dressing, Paint

Question 14

Molecules

Answer 14

Two or more atoms are joined together chemically. Elements can be different or the same.

Example: O + O = O2

Question 15

Matter

Answer 15

Anything that has a mass and a volume. Atoms and molecules are all composed of matter. Matter is anything that has mass and takes up space

• There are three states of matter: Solids, Liquids, and Gases
• Matter takes up space
• Matter has its own properties. Shape, size, color, smell, and temperature are all examples of the properties
• Matter also has mass.
• Matter can change.
