The lower the pH the higher the concentration of H+ ions in an acid. The higher the pH the lower the concentration of H+ ions (and the higher the concentration of OH- ions) in an alkali.

What are the equations for reactions with metal oxides, hydroxides and carbonates?
Acid + metal oxide/hydroxide = salt + water. Acid + metal carbonate = salt + water + carbon dioxide.
3 of 5
Name common acids and the salt names.
Nitric acid produce nitrates, sulfuric acid produce sulfates, phosphoric acid produce phosphates and hydrochloric acid produce chlorides.
4 of 5
What is the neutralisation equation (give an example)?
Acid + base = salt + water. For example, sulfuric acid + sodium hydroxide = sodium sulfate + water.
