(a) *describe the techniques used in the preparation, separation and purifi cation of salts as examples of
some of the techniques specifi ed in Section 1.2(a)
(methods for preparation should include precipitation and titration together with reactions of acids
with metals, insoluble bases and insoluble carbonates)
(b) describe the general rules of solubility for common salts to include nitrates, chlorides (including silver
and lead), sulfates (including barium, calcium and lead), carbonates, hydroxides, Group I cations and
ammonium salts
(c) suggest a method of preparing a given salt from suitable starting materials, given appropriate
information
(d) describe the meanings of the terms hydrated, anhydrous and water of crystallisation
