2.34 Solubility rules

Know the general rules for predicting the solubility of ionic compounds in water:

• common sodium, potassium and ammonium compounds are soluble
• all nitrates are soluble
• common chlorides are soluble, except those of silver and lead(II)
• common sulfates are soluble, except for those of barium, calcium and lead(II)
• common carbonates are insoluble, except for those of sodium, potassium and ammonium
• common hydroxides are insoluble except for those of sodium, potassium and calcium (calcium hydroxide is slightly soluble).
