4.6 understand the general rules for predicting the solubility of salts in water: i all common sodium, potassium and ammonium salts are soluble ii all nitrates are soluble iii common chlorides are soluble, except silver chloride iv common sulfates are soluble, except those of barium and calcium v common carbonates are insoluble, except those of sodium, potassium and ammonium

General rules of solubility

Soluble salts

• all common sodium, potassium and ammonium salts
• all nitrates
• all common chlorides (except silver and lead (II) chloride)
• all common sulfates (except barium,calcium and lead (II) sulfate)
• sodium, potassium and ammonium carbonates

Insoluble salts

• silver chloride and lead (II) chloride
• barium sulfate, calcium sulfate and lead (II) sulfate
• all other common carbonates
