Guest guest Posted February 2, 2008 Report Share Posted February 2, 2008 The PH of a given soft drink is the same whether it is diet or regular. The quantity of phosphoric acid in a soda is so small, it has a miniscule impact on the overall acidity of the soda, which is about 3. This comes from carbonic acid, which is part of the carbonation process, or the bubbling if you will. The stomach PH, being basically 1, would be unaffected by the soft drink. If you drink enough, the stomach will turn on it's acid generators, and more acid with a PH of 1 arrives. Looks like the sugar that is in regular soft drinks, and isn't in diet softdrinks, is probably the culprit. Don White Seguin, Tx Quote Link to comment Share on other sites More sharing options...
