Sodium Carbonate. Sodium carbonate is a sodium salt of carbonic acid and a strong base. It is supplied as a white, odorless powder that is hygroscopic and very soluble in water producing a strong alkaline solution.
Calcium carbonate isn't harmful at all (unless there's so much that it suffocates the organisms). Most marine life needs calcium carbonate to make shells and bones.Since sodium carbonate isn't so vital I suppose it qualifies as more harmful.Don't confuse it with the rather harmless sodium hydrogen carbonate or sodium bicarbonate.) I think using washing soda (sodium carbonate) in the house is not a big environmental issue because it is harmless when dissolved. Neutralization of sodium carbonate with hydrochloric acid will produce sodium chloride.
