Hi everybody,
i bought a bottle of commercial sulfuric acid used to clear the drainage pipes.
Its concentration is 65 Bé (98%), but isn't clear: it is dark brown, and on the label is written that there are some corrosion inhibitors, but aren't specified names.
Now, how can i do to separate the brown dye (if it is present) and the corrosion inhibitors from the sulfuric acid? Because i don't know what they are !
Thank you :), i'm sorry for the bad english :(
