Solubility Rules
Captions available
The idea
Solubility rules are an empirical classification scheme naming which ionic compounds are generally soluble or insoluble in water.
In practice
All common nitrate salts are soluble, but most common carbonate salts, apart from the group 1 metals and ammonium, are insoluble.
Where people slip
Skipping a listed exception, such as ammonium among carbonates, misapplies a solubility rule as if it had none.
