Do you mean muriatic acid and hydrogen peroxide? Those are not hazardous chemicals, if they are neutralized. The hydrogen peroxide is easy to neutralize; just put a piece of charcoal in the bottle and it should decompose. Exposing it to sunlight will also work. Muriatic acid could be harder, depending on the concentration. You just need to react it with base. Sodium bicarbonate, ammonia, and powdered drain cleaner are all readily available bases. But if the acid is highly concentrated, you will need to mix carefully because the reaction is exothermic. First pour water into a container, then mix in a calculated amount of base, then slowly pour in the acid. I don't know the relevant environmental regs, but I'm sure that at pH 5-9 those chemicals should be safe for any sewer.
Are the muriatic acid and H2O2 already mixed together? I don't think that H2O2 has an adverse reaction with most bases. NaOH will probably just catalyze its decomposition. But IANAC (I am not a chemist). On Thu, Jan 20, 2011 at 9:43 AM, Rob Butts <r.but...@gmail.com> wrote: > I have excess muratic acid/hydrogen per oxcide etch solution after > making a board.
