What level is Coke Zero on the pH scale?

Answer 1

The pH of coke, Diet Coke and Coke Zero is approximately 3. Published research in peer reviewed publications puts coke as the most acidic of the three. The acidity of these beverages is due in large part to the presence of phosphoric acid as an added ingredient. Phosphoric acid is a weak acid. Furthermore, the lack of any significant buffering in sodas means that these types of beverages incapable of significantly altering your stomach pH. In fact, recent peer reviewed research shows that coke and diet coke pH will increase to approximately 5 to 6 in your mouth. The pH of your stomach becomes very acidic in response to the presence of food proteins (pH of 1.5 to 2). If you do the math, you can see that these beverages do not have an acidic effect on your stomach, much less effect your entire body. Note also that our physiology has the capacity to adjust to changes in blood pH by three mechanisms: buffers in blood, respirations (breathing) increases to remove acid from the blood, in kidney you will excrete (urinate) more acid if there is any change in blood pH. For these reasons, blood pH does not vary beyond a pH of 7.4 to 7.6. It is very tightly regulated by automatic physiological processes.

Answer 2

Well coke zero is about 1-2 on a pH scale but normal coke is about 3-4 but diet coke is about 8-9 which is weird because like all coke is like an acid!!

Thanks for your time by the way this is cool because you can type your own answers on here!! WOW!

Coke Zero is actually NOT 1-2 on the pH scale because that is about battery acid and stomach acids level, which are really, really acidic. Lemon juice and vinegar are only 3 on the pH scale. So Coke Zero is really around 4.
