Why is cola an acid?
How acidic is Coke? Its pH is reported to be 2.6 to 2.7, mainly due to H3PO4, phosphoric acid. As a fizzy drink, it contains plenty of dissolved carbon dioxide, but this makes very little contribution to the acidity.
What is the main acid in Coca Cola?
phosphoric acid
Coca‑Cola European Partners use a very small amount of phosphoric acid in some of the Coca‑Cola system’s soft drinks, such as Coca‑Cola Classic, Diet Coke, Coca‑Cola Zero Sugar and Dr Pepper.

Does Coke dissolve steak?
According to UCSB ScienceLine, stomach pH is usually around 2. Therefore, with Coke’s pH of 2.37, it should be able to dissolve meat as well. The experiment shows that even though it does tenderize the meat, Coke will not completely dissolve the meat after soaking for one week.
Will Coke dissolve?
So, what can Coca cola dissolve? Coke can dissolve anything that can dissolve in water. The myth that you can dissolve a quarter or a nail in a glass of Coke. But, it has been debunked through experiments and nothing happens even if you leave it in for 7 days.
Where does the acidity in Cola come from?
Most of the acidity in colas comes from phosphoric acid, whose chemical formula is H (3)PO (4). Some sodas contain acids in addition to the three most common ones.
Why is phosphoric acid used in some Coca ‑ Cola drinks?
To add to their taste. Coca‑Cola European Partners use a very small amount of phosphoric acid in some of the Coca‑Cola system’s soft drinks, such as Coca‑Cola Classic, Diet Coke, Coca‑Cola Zero Sugar and Dr Pepper. It gives them their tartness.

How does the sugar in Coca Cola affect the pH?
The sugar in the Coke fools us into thinking Coca-Cola is not acidic but it doesn’t actually affect pH levels. This means that we can’t really tell Coca-Cola’s pH just by tasting it.

What is the pH of a Cola base?
I am of the opinion that this is the correct answer. My reasoning is that the pH of most colas is on the order of 2-4, and the pKa of carbonic acid is about 6. You’d need a hell of a lot of carbonic acid to get to that pH, while the pKa of phosphoric acid is 2.1, so it’d be quite easy to get to a pH of, say, 3. – chipbuster Sep 9 ’13 at 17:11
