    I found this answer by googling for "ferric chloride disposal":

    One thing to note - when you add baking soda to ferric chloride,
    it's goingto create small amounts of carbon dioxide, especially if
    the the ferric chloride is fresh. This will foam up, so do it slowly
    at first. 

    Not only jewelers use ferric chloride - sculptors, printers, and
    people making printed circuit boards also use it, so the local
    hazardous waste disposal folk will be extremely familiar with it. 

    The other thing to note is that you can use your ferric chloride
    solution longer if you mix in citric acid powder (which you can get
    at health supplement stores).
