Hi chaps
I've been finding it difficult to get citric acid, as shops like Boots just
don't seem to stock home brew equipment any more. However, I've just found
that a mail order company, the Home Brew Shop (www.the-home-brew-shop.co.uk)
can supply 1kg tubs for 4UKP, which I think is pretty good. The downside is
that the postage is 6.50UKP, however I've ordered two tubs and that should
last me some time.
In my workshop I have a spent tank of sulphuric acid - it contains so much
dissolved copper that it is probably mostly copper sulphate now. Does anyone
know of a safe/legal way to dispose of it? Could I mix an alkali with it to
neutralise it, and if so would it be safe to tip down the drain? I expect
this might still be taboo on account of the dissolved metal. Any ideas
anyone?
