What happens when alkaline earth metals are combined with hard water?
Temporary hard water contains bicarbonate (HCO3–) which forms CO3–2(aq), CO2(g), and H2O when heated. The bicarbonate ions react with alkaline earth cations and precipitate out of solution, causing boiler scale and problems in water heaters and plumbing.
