    Sodium hydroxide absorbs moisture from the air. It has a specific gravity
    of 2.13.
    Sodium carbonate does do much with the moisture normally found in the air.
    It has a specific gravity of 2.53.

    If the containers are transparent, and of the same dimensions, if you tamp
    them both down, the sodium hydroxide should look "more full".
