CSS_SV Posted March 30, 2015 Posted March 30, 2015 Can I effectively neutralize sodium hypochlorite 12.5% with hydrogen peroxide? If so, what percentage should I use? If not, what else could I use? Thank you in advance!
Enthalpy Posted March 30, 2015 Posted March 30, 2015 And peroxide certainly isn't the first idea to "neutralize" a solution. Before mixing two meta-stable oxygen-rich compounds, are there incompatibilities?
studiot Posted March 30, 2015 Posted March 30, 2015 Dilution with water is the connventional way of dealing with common or garden bleach concentrate. About 250 parts water to 1 part concentrate by volume is about right for your original strength.
John Cuthber Posted March 30, 2015 Posted March 30, 2015 Peroxide will certainly destroy bleach,and fairly cleanly too. ( the products are salt water and oxygen.) But the reaction is vigorous- possibly dangerous on anything but a very small scale. Also, the easiest way to destroy hypochlorite is simply to wait. It decomposes to salt water and oxygen (though it takes a few years)
CSS_SV Posted March 30, 2015 Author Posted March 30, 2015 I use a 50 gallon mixture roughly 32 gallons of water and 18 gallons of sodium hypochlorite 12.5% to clean the exterior of houses. I'm looking to neutralize the effects of the bleach so that no plants or grass is damaged if it comes down the gutters. Thanks.

If you neutralise it before you use it, it won't do the job you want it to do. It is a good cleaner and mould-killer because it is so reactive. As long as you don't use the thickned stuff with gel in it, it will completely evoaporate away just fine. You can't stop it harming green stuff and expect it to be useful. The best you might do is thoughly hose water over those areas ASAP after the job is done.
studiot Posted March 30, 2015 Posted March 30, 2015 All you need is to place an expanding drain pipe stopper in each downpipe before starting and then flush with water at the end. 1
John Cuthber Posted March 31, 2015 Posted March 31, 2015 Salt water is bad for most plants so you would still need to wash it away when you had finished.
