I wish to know few details about ferric chloride.
1. Ferric chloride alone (not used), can be disposed in our soil , no harms?
2. I have few newspaper pieces stained with Ferric chloride (may have copper because used for etching), is it safe to burn this paper ?
3. After etching I remove the solution from 1st container to second container, is if safe to wash this 1st container in tap outside the house?
4. How much copper is safe if somehow fallen outside on the house soil.
5. My ferric chloride solution, is only around 200 ml, after continuous etching over a year it has turned dark brown. can I dry it in hot sun and
keep it safe as powder ? ( or heat or melt it in to a solid substance like piece of copper?
