Hello,
Im raising my exhausted waste acid to around 2.5 PH with Soda ash then, I use very small iron trim nails added to drop the copper ( I have a LOT of trim nails from the old days before airguns took over, so my iron hoard is a big freebee) & other metals in the acid.
My question is one about safety from a health standpoint, I have several bottles of Drain cleaner thats main ingrediant is Sodium Hydroxide, which is obviously good for dropping iron but, the bottle also states it contains Sodium Hypochlorite & Sodium Silicate. Im not heating the solution at all, so will there still be a dangerious Chlorine gas possibility? If so Ill take it back & buy just pure Sodium Hydroxide if it is.
I searched but could not find an answer to this question, but I may have searched in a incorrect manner of wording I don't know. I just want to be as safe as possible at all times.
Thanks in advance,
Dave
