Doc Brown's Chemistry GCSE/IGCSE Science-Chemistry Revision Notes

The pH scale of acidity and alkalinity, acids, alkalis, salts and neutralisation

6. Methods of making salts

Original page now split into four sections, NEW links below

How do we make salts? What preparations are available to us?

Four basic methods for preparing salts are described on this page, with annotated diagrams.

BEFORE preparing a salt there are two important facts to know ...

(i) Is the salt is soluble or insoluble?

(ii) If using a base, is it soluble (alkali)? or insoluble?

... because facts decide which method you use!

Method (a) Making a salt by neutralising a soluble acid with a soluble base (alkali) - neutralisation reaction

Method (b) preparing a salt by reacting an acid with a metal or with an insoluble base - oxide, hydroxide or carbonate

Method (c) Preparing an insoluble salt by mixing solutions of two soluble compounds

Method (d) Making a salt by directly combining its constituent elements
