How much acid is in orange soda and hence what is the pH?

Orange soda typically contains citric acid and phosphoric acid, with citric acid being the predominant acid. The concentration of acid can vary, but it often ranges from 0.5% to 1% citric acid. This level of acidity usually results in a pH value between 2.5 and 3.5, making orange soda quite acidic compared to neutral beverages.
