Acids and bases - 9.5.3: The reactions of dilute acids
- 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
- 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
Expt: The reaction of acids
The neutralisation process. Everyday examples to be taken from farming
and the kitchen.
Expt: Preparation of a salt
The concept of solution concentrations, units g/dm3
and moles/dm3. The relationship between litres
Introduction to the apparatus used for titrimetric analysis: Burette,
pipette, pipette filler.
Expt: Titration of an
acid and a base.
Construction and balancing acid/base equations
Salt preparation:- method a, b or c dependent on salt solubility.
- a: acid + excess base
- b: soluble acid + soluble base
- c: precipitation
Expt: Planning to produce a dry sample of a given salt
