Orange juice is acidic despite its sweet taste. The wide array of juices you can find on grocery store shelves and in the farmers market -- or that you can make at home -- can all be categorized as acidic, alkaline or neutral, depending on their pH level. The lower the pH level is, the more acidic the juice. The acidic range on the pH scale is anything below 7, which is considered neutral. While you might associate acidic juices with a sour taste -- as with lemons and limes -- other acidic juices, such as apple and orange, are often naturally sweet despite their pH levels.
