I was working through a past paper (2013) and one question mentioned something about disposing of lead safety, an I was a bit confused because we were never taught how to do it and my teacher just lets everyone pour it down the sink, sort came up with a half decent response (evaporating water to leave lead ions which can be safely stored away). anyways it made me we eren't taught to do this properly. Does anybody else school allow this? How do you dispose of chemicals safely?
