Looking for some help with this one... I'm having an arguement with a friend of mine, a supposed graduate of Purdue (Aero Eng) who seems to think that all one has to do to make hydrochloric acid (admittedly, a weak one) is to mix table salt with water: NaCl + H2O > HCl + NaO I admit that it has been a long while since I took engineering chemistry, but this is a ridiculous assertion. First off, the chemical equation isn't balanced, second, there has to be some sort of catalytic reaction to promote this, and third, the most obvious, I'd get acid burns everytime I went to the beach. Could someone please give me supported evidence that I can use to convince this guy that just because it is on paper doesn't make it so? Also, is seawater in fact, acidic? At the same time, if I'm wrong, I'd like to know that as well. I look forward to hearing from you.
