Sep 04, 2016· Citric acid is a polyprotic acid (can release three H + s) that is a bit on the weak side (i.e., tends not to ionize completely). In solution in fruit juices, it lets a small portion of the H + go, however this small amount of acid is enough to create a pH = ~3 solution and a sharp taste on the palate.
