diggemall said:BTW – the Ph of carbonic acid at atmospheric pressure is about 5.6. Orange and Lemon Juice have a Ph of about 2.8, vinegar is about 3.0, and your own stomach acid has a Ph of about 1.2 – that’s why it burns when you puke. (the lower the number, the stronger it is - 7.0 is neutral)

It's the phosphoric acid in Coke that gives it such a low ph (about 2.5 to 3). Carbonic acid is much weaker because it doesn't ionize as completely. it still corrodes things after a while, though.
