A patient regularly drinks soda. What is the most commonly cited approximate pH of typical soft drinks (especially colas)?
Show answer and explanation
Correct answer: A. About 2.5 (quite acidic, comparable to or more acidic than gastric contents in some cases)
Most carbonated soft drinks, especially colas, have a pH around 2.5 (commonly cited range roughly 2.3–3.5 depending on the specific beverage), making them quite erosive to dental enamel with frequent or prolonged exposure — well below the critical pH (~5.5) at which enamel begins to demineralize.
