Melanie ShebelThis answer on a question regarding whether water is corrosive in pure form, the author implies that "reactive" and "corrosive" are the same thing (at least with water.) "Corrode" seems to mean irreparably damaged which also seems to imply a corrosive reaction is not reasonably reversible where "...

Q: What's wrong with my question?

JoeSlavQuestion: Calculate concentration of Benzalkonium chloride with dilution From my perspective: Is it related to chemistry? yes Is it a low effort post? no; clearly asked what I need and provided example of possible solution for which I am seeking validation Now, is it an easy question? Probably....
