1
Q

The pH scale is a measure of the concentration of

A

hydrogen ions

2
Q

A pH below 7 is

A

Acidic

3
Q

A pH above 7 is

A

Alkaline

4
Q

pH 7 is

A

neutral

5
Q

Acidic solutions have a higher concentration of

A

H+ ions (hydrogen)

6
Q

All acids contain ions and as a result

A

conduct electricity because the ions are free to carry the charge

7
Q

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

A

decreased. So the pH moves towards 7.

8
Q

Alkaline solutions have a higher concentration of

A

OH- (hydroxide ions).

9
Q

Alkalis contain ions and as a result

A

conduct electricity

10
Q

Acids and alkalis are formed by

A

dissolving different oxides in water.

11
Q

Soluble non-metal oxides produce

A

acids

12
Q

Soluble metal oxides (bases) produce

A

alkalis

13
Q

Neutralization reactions produce

A

a salt and water

14
Q

The salt in this reaction would be:

hydrochloric acid + sodium hydroxide——–> ________ + H2O

A

Sodium Chloride

15
Q

Spectator ions are ions that are

A

present during the reaction but remain unchanged by the reaction

16
Q

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

A

Carbon Dioxide

17
Q

A titration is an acid base procedure used to determine

A

the concentration of an acid

18
Q

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

A

The number of ‘H’s and acid or alkali has
