Syllabus Objectives
At O levels, students are required to 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
Solubility Rules
Chlorides
All chlorides are soluble except lead(II) chloride and silver chloride.
Carbonates
All carbonates are insoluble except Group I metal carbonates and ammonium carbonates.
Sulfates
All sulfates are soluble except calcium sulfate, lead(II) sulfate, barium sulfate.
Nitrates
All nitrates are soluble.
Group I and ammonium salts
All Group I metal salts and ammonium salts are soluble.
