Hi Ed,

Then the following instruction would be suitable:
http://www.realscience.breckschool.o...5/Website.html
wherein it states:
"Parietal cells in the stomach lining secrete HCl. The pH level of
the stomach ranges from 1.5 to 3.5. The molarity of the HCl is then
approximately 0.01 M.
... "Coca Cola is acidic because the reaction between carbon
dioxide and the other ingredients of the soda produces carbonic acid.
Coca Cola Classic has a pH of 2.5..."


coca cola also has phosphoric acid in it
