Does anyone know if NaHCO3 is a hydrate?

I calculated it has 20% water. Can you give me the formula say NaHCO3 *H2O. The * standing for the number of water to sodium bicarbonate

    Let's say you have 100 g NaHCO3. That means that 20% of the weight is from water, so you would have:

    80 g NaHCO3

    20 g H2O

    80 g NaHCO3 (1 mol / 84.01 g NaHCO3) = 0.952 mol NaHCO3

    20 g H2O (1 mol / 18.01 g H2O) = 1.11 mol H2O


    Divide by the least amount to get whole numbers:

    NaHCO3 * H2O = NaHCO3•H2O

    Source(s): I don't think sodium bicarbonate can form hydrates.

    NaHCO3 is a decomposes at 65 degree c to give Na2CO3 + CO2 + H2O

    There is no formula of NaHCO3 that exists as NaHCO3.XH2O....

    It decomposes to give Na+ and HCO3 minus

    NaHCO3 is not a hydrate

    Na2CO3 + CO2 + H2O on cooling gives NaHCO3

    No water of crystallisation is associated with sodium hydrogen carbonate.
