Chapter 3 Acids, Bases, And Solutions

Front 1

solution

Back 1

A well-mixed mixture that contains a solvent and at least one solute

Front 2

Solute

Back 2

the substance present in a solution in a smaller amount

Front 3

Solvent

Back 3

the part of a solution present in the largest amount

Front 4

colloid

Back 4

A mixture containing small, undissolved particles that do not settle out.

Front 5

suspension

Back 5

A mixture in which particles can be seen and easily separated by settling or filtration.

Front 6

Dilute solution

Back 6

A mixture that has only a little solute dissolved in a certain amount of solvent

Front 7

Concentrated Solution

Back 7

A mixture that has a lot of solute dissolved in a certain amount of solvent

Front 8

solubility

Back 8

A measure of how much solute can dissolve in a solvent at a given temperature

Front 9

Saturated solution

Back 9

when so much solute has been added that no more can dissolve

Front 10

Unsaturated solution

Back 10

when more solute can be dissolved in a solution

Front 11

Supersaturated solution

Back 11

a solution that has more solute dissolved that is predicted by its solubility at the given temperature

Front 12

Acid

Back 12

a substance that tastes sour, reacts with metals and carbonates, and turns blue litmus paper red

Front 13

Base

Back 13

a substance that tastes bitter, feels slippery, and turns red litmus paper blue

Front 14

Corrosive

Back 14

a property of matter where the substance 'eats away' at other materials

Front 15

Indicator

Back 15

a compound that changes color when in contact with an acid or base

Front 16

Hydrogen Ion

Back 16

a positively charged ion formed of a hydrogen atom that has lost its electron. (makes a solution acidic)

Front 17

Hydroxide Ion

Back 17

A negatively charged ion made of oxygen and hydrogen (makes a solution basic)

Front 18

pH scale

Back 18

a range of values from 0 to 14 that expresses the concentration of hydrogen ions in solution

Front 19

Neutralization

Back 19

A reaction between an acid and a base that yields a solution that is not as acidic or basic as the starting solutions were.

Front 20

Salt

Back 20

An ionic compound made from the neutralization of an acid with a base

Front 21

Digestion

Back 21

process of breaking down the complex molecules of foods into smaller molecules

Front 22

Mechanical digestion

Back 22

physical process in which large pieces of food are torn and ground into smaller pieces

Front 23

Chemical digestion

Back 23

the process of breaking down large molecules in food into smaller molecules using chemical reactions
