• Understand that acid is a general term for a group of chemicals

• be able to use and predict the effect of indicators on acids and bases.

• be able to recall the three mineral acids with their formulae and state the salts formed by them.

• recognise the presence of the H+ ion as the cause of acidity and the OH- ion as the cause of basicity

• understand the use of moles in calculation of concentration

• recall and construct equations for the four common reactions of acids.

• work with care and recognise the dangers associated with corrosive substances.
