1

Acids

Hydrogen in formula
When dissolved in water, an acid releases hydrogen ions as protons into solution

2

Strong acids

Release all hydrogen atoms into solution and completely dissociates in an aqueous solution

3

Weak acids

Partially dissociates in an aqueous solution
Only 1 in every 100 molecules dissociate
Organic acids are weak

4

Bases

Oxides, hydroxides, carbonates, ammonia are bases
Bases neutralise acids to form a salt

5

Alkalis

Dissolve in water, releases OH-

6

Neutralisation

Metal oxide + acid = salt + water
Metal carbonate + acid = salt + water + carbon dioxide
Metal + acid = salt + hydrogen

7

How to form ionic equations

Write out ions of all aqueous compounds
Cross out ones that are on both sides
