1

pH of acids

Less than 7

2

pH of alkali

More than 7

3

An acid is a source of...

hydrOGEN ions (H+)

4

A base is...

a substance which can neutralise an acid. Alkalis are soluble bases.

5

An alkali is a source of...

hydrOXIDE ions (OH-)

6

Neutralisation reaction

The reaction between and acid and a base:
acid + base --> salt + water

or, H+(aq) + OH-(aq) --> H2O
The products are neutral.

7

What is the name of the reaction between and acid and a base?

Neutralisation.

8

Reaction between acids and metal oxides or metal hydroxides

Metal oxides/hydroxides are usually bases so they react the same way.
acid + metal oxide/hydroxide --> salt + water

The salt produced is determined by the acid used:
sulfuric acid + copper oxide --> copper sulfate + water

9

Reaction between acids and metal carbonates

acids + metal carbonate --> salt + water + carbon dioxide

The salt you get depends on the acid you used:
hydrochloric acid + sodium carbonate --> sodium chloride + water + carbon dioxide

10

Hydrochloric acid

HCl

11

Sulfuric acid

H2SO4

12

Nitric acid

HNO3

13

Reaction between acids and metals

acid + metal --> salt + hydrogen
