Bc Science 10 - Chapter 5

Front 1

pH scale

Back 1

A number scale for measuring how acidic or basic a solution is.

Front 2

bases

Back 2

Chemical compounds containing hydroxide that produce a solution with a pH of more than 7 when dissolved in water, produce a salt and

water when they react with ionic compounds containing positive hydrogen ions.

Front 3

neutral

Back 3

Neither acidic nor basic: describes a solution with a pH of 7

Front 4

corrosive

Back 4

biting; describes some acids and bases that can burn or eat away many materials, such as metals and human tissue.

Front 5

pH indicators

Back 5

Chemicals that change colour depending on the pH if the solution they are placed in.

Front 6

litmus paper

Back 6

Thin paper strips coated with litmus and used

as an acid-base indicator, turning one colour when added to a base, and a different colour when added to an acid. Litmus is a compound extracted from various lichens.

Front 7

phenolphthalein

Back 7

A chemical compound that is colourless in acidic or slightly basic solutions but turns pink in moderately basic to highly basic solutions.

Front 8

bromothymol blue

Back 8

An acid-base indicator named after its colour change from yellow to blue over a pH range of 6.0 to 7.6.

Front 9

indigo carmine

Back 9

an acid-base indicator named after its colour change from blue to yellow over a pH range of

11.2 to 13.0.

Front 10

methyl orange

Back 10

An acid-base indicator named after its colour change from red to yellow over a pH range of

3.2 to 4.4.

Front 11

methyl red

Back 11

An acid-base indicator named after its colour change from red to yellow over a pH range of

4.8 to 6.0.

Front 12

caustic

Back 12

harsh; describes solutions made from highly reactive bases, such as drain cleaner and oven cleaner.

Front 13

hydroxide ions

Back 13

Negative ions of OH~~; can be produced when bases are dissolved in solution.

Front 14

hydrogen ions

Back 14

Electrically charged hydrogen atoms can be

produced when acids are dissolved in solution.

Front 15

concentration

Back 15

The amount of substance dissolved in a given volume of solution - for example, the number of hydrogen ions in a specific volume of solution.

Front 16

neutralization

Back 16

The chemical reaction that occurs when an acid and a base react to form a salt and water.

Front 17

metal oxide

Back 17

A compound containing a metal chemically

combined with oxygen.

Front 18

non-metal oxide

Back 18

A chemical compound that contains a non-metal chemically combined with oxygen.

Front 19

organic

Back 19

Refers to almost all carbon-containing compounds; exceptions include carbon dioxide, carbon monoxide and ionic carbonates.

Front 20

inorganic

Back 20

Refers to compounds that generally do not contain carbon; the few exceptions include carbon dioxide, carbon monoxide, and ionic carbonates.

Front 21

organic chemistry

Back 21

The study of compounds that contain carbon

Front 22

alcohol

Back 22

One kind of organic compound that contains C,H, and O, such as methanol and ethanol.

Front 23

hydrocarbon

Back 23

An organic compound that contains only the

elements carbon and hydrogen.

Front 24

Solvent

Back 24

A liquid that can dissolve other substances.

Front 25

Salts

Back 25

A class of ironic compounds that can be formed during the reaction of an acid and a base.
