[sdiy] Disposing of cupric chloride

[Karl Ekdahl]

Hi list, so i had a little acid spill and need to dispose of some cupric chloride but haven't found any straight answers on how to. I neutralized the solution using water and baking soda, and then i put a beer can in the mix as i heard aluminium will form crystals with the copper which would be way easier to dispose of then the liquid form. Long story short i've ended up with a bucket of blue water with what looks to be salt in the bottom. I assume the "salt" is the copper, now can i simply pour the blue water in the drain or is it still super poisonous?

Thanks

Karl
