WebApr 9, 2024 · Weak Acids. A weak acid is the one that fails to ionize in the solution completely. It releases H + ion in the low concentrations, and thus pH ranges from 5 to 7. Some of the examples include formic acid (HCOOH), acetic acid (CH 3 COOH), and many more. Weak Bases. Weak bases are the substances that do not undergo complete … WebIn the case of a weak acid versus a strong base, the pH is not neutral at the equivalence point.
