1

The pH scale is a measure of the concentration of

hydrogen ions

2

A pH below 7 is

Acidic

3

A pH above 7 is

Alkaline

4

pH 7 is

neutral

5

Acidic solutions have a higher concentration of

H+ ions (hydrogen)

6

All acids contain ions and as a result

conduct electricity because the ions are free to carry the charge

7

When an acid is diluted with water the concentration of H+ ions is

decreased. So the pH moves towards 7.

8

Alkaline solutions have a higher concentration of

OH- (hydroxide ions).

9

Alkalis contain ions and as a result

conduct electricity

10

Acids and alkalis are formed by

dissolving different oxides in water.

11

Soluble non-metal oxides produce

acids

12

Soluble metal oxides (bases) produce

alkalis

13

Neutralization reactions produce

a salt and water

14

The salt in this reaction would be:
hydrochloric acid + sodium hydroxide--------> ________ + H2O

Sodium Chloride

15

Spectator ions are ions that are

present during the reaction but remain unchanged by the reaction

16

When an acids reacts with a metal carbonate asides from salt and water, what else is produced

Carbon Dioxide

17

A titration is an acid base procedure used to determine

the concentration of an acid

18

PVC (acid) = PVC(alkali), what does the P stand for?

The number of 'H's and acid or alkali has
