Name acidic foods

There are a lot of food acids. Most food acids end in the "ic" suffix.

Like Citric Acid, Malic Acid, TarticAcid, Asorbic Acid, Vinegar, Acetic Acid, Folic Acid, Sodium Acid, Tactic Acid, Stearic Acid, and Tumeric. That's all that I could think of right now, but there are many more. I hope this helps,
