  1. 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)

  5. 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.
