Students in my classes usually report false information regarding phosphoric acid in Coca Cola.According to Snopes http://www.snopes.com/cokelore/acid.asp, Coca Cola contains 11 to 13 g phosphoric acid per gallon of syrup. This works out to be 0.20 to 0.30% of the total formula. The syrup is diluted with carbonated water for serving so that should reduce the phosphoric acid to 0.02 to 0.03% or less.David_________________________________________________________________________

There is a part A and a part B - the part B has phosphoric acid - both MSDSs (SDSs) put out by the company indicate irritation if ingested at large dosages.I think he needs to have an IH talk with him.

Hey Frank,I would gladly take you up on your offer to be put in touch with any colleagues you think might be able to help.One of the most popular water treatment options amongst Appalachian Trail thru-hikers is Aquamira, a chlorine dioxide chemical solution. As you point out, the dose makes the poison- however due to the extreme demands of long-distance backpacking, it's common to ingest between 5-8 liters of water per day. Multiply this times 4-6 months (how long it takes to cover the full distance of the trail). Since my thru-hike in 2011, I have battled severe digestive issues, and I have talked with others (who've used Aquamira) who say the same. If there is any truth to this being unsafe in high volumes, I'd like to help spread the word and prevent future hikers from suffering.Any help you can offer would be greatly appreciated.Best,Zach

Pitch Title: Your request on chlorine dioxide
You really need to contact the American Chemical Society - they can put
you in touch with the correct person. My recommendation is that you need
to talk with an industrial hygienist as they are more trained in how
chemicals are used/misused and toxicity levels. A chemical toxicologist
is someone else you might talk with. I can put you in touch with a
couple of colleagues of mine that may be able to help. As with most
things it is a matter of dose.
