Acids and bases - 9.5.3: The reactions of dilute acids


Students should…

  • 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.


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 and cm3

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
