According to Jain, Nihill, Sobkowski, and Agustin, in Commercial soft drinks: pH and in vitro dissolution of enamel (General Dentistry, March/April 2007 , Volume 55 , Issue 2 - http://www.agd.org/publications/articles/?ArtID=923) cola drinks fell into a pH range of approximately 2.4 - 3.3 (with most being below pH 3.0) whilst non-colas had a pH range of approximately 2.9 - 3.7 (all but one measured was over pH 3.0). Iced teas came in at around pH 2.9
