react each with a dilute strong acid, such as sulfuric acid
the NaHCO3 will leave a clear solution (sodium ) after bubbling
NaHCO3 + H2SO4(aq)>>> CO2 (g) + H20 + Na2SO4 (in solution)
Calclum will leave a NOT clear liquid (Calcium)
Ca(HCO3)2 + H2SO4(aq)>>> CO2 (g) + H20 + CaSO4 (precipate)
the NaHCO3 will leave a clear solution (sodium ) after bubbling

In separate test tubes boil about 5cm3 of each solution. Sodium hydrogen carbonate solution remains colorless and forms no precipitate. Calcium hydrogen carbonate solution changes from colorless to a white precipitate.
