Sodium carbonate, Na2CO3, is quite soluble. Sodium bicarbonate, NaHCO3, is quite soluble too, but it's already in the intermediate form (i.e. protonated once, when compared to the carbonate ion, CO3--).
I just looked up the Material Safety Data Sheet for sodium carbonate (washing soda). Do not ingest this substance!
I think sodium bicarbonate is the one being promoted for use in this role because it provides the safest and most effective activity, all thing considered.
