WHat is ph of coke?

Answer 1

The active ingredient in Coke is phosphoric acid. Its pH is 2.8. It will dissolve a nail in about 4 days.

"The active ingredient in Coke is phosphoric acid." An active ingredient is defined as: "a component or mixture that performs the function of the product". What exactly is the function of Coca-Cola? According to the Coca-Cola web site, Coca-Cola does not perform any function, other than to provide "true refreshment" (a bit vague of a function if you ask me). To that end, I would be inclined to believe that the sugar and water in Coke are more likely to be called "active ingredients" than phosphoric acid, although phosphoric acid does contribute to the taste of Coke.

"Its pH is 2.8." Its pH may very well be 2.8, but with the amount that is actually in a can of Coke, I'm sure that the other ingredients buffer it. Ever drink a glass of wine? Good quality wine has a pH of about 2.9. pH of 2.8 is about the pH of lemon juice. A pH of 2.8 might make your mouth pucker, but it won't hurt you.

"It will dissolve a nail in about 4 days." What will? Based on elementary school English, the subject of the first sentence is phosphoric acid. The "it" in the second and third sentences are pronouns referring to phosphoric acid in the first sentence. That means that phosphoric acid will dissolve a nail in about 4 days. What does that have to do with Coke? Is it the only ingredient in there? I have hydrochloric acid in my stomach with a pH of 2...if I hold a nail in my hand for four days, will it dissolve? Again, the other ingredients in Coke will buffer the relatively small amount of phosphoric acid found in Coca-Cola.
