Therefore, pH values on the different scales cannot be compared directly because of differences in the solvated proton ions, such as lyonium ions, which require an insolvent scale that involves the transfer activity coefficient of hydronium/lyonium ion. pH is an example of an acidity function, but others can be defined.
The isoelectric point (pI, pH(I), IEP), is the pH at which a molecule carries no net electrical charge or is electrically neutral in the statistical mean. The standard nomenclature to represent the isoelectric point is pH(I). [1] However, pI is also used. [2] For brevity, this article uses pI.

Most commonly, the meaning of "DW" in text is "don't worry." (Doctor Who or Arthur fans everywhere may disagree.) This meaning applies to social media platforms such as Facebook and Instagram as well.
Phenol is a weak acid (pH 6.6). In aqueous solution in the pH range ca. 8 - 12 it is in equilibrium with the phenolate anion C 6 H 5 O − (also called phenoxide or carbolate): [10] C 6 H 5 OH ⇌ C 6 H 5 O − + H + Resonance structures of the phenoxide anion
Intracellular pH (pH i) is the measure of the acidity or basicity (i.e., pH) of intracellular fluid. The pH i plays a critical role in membrane transport and other intracellular processes. In an environment with the improper pH i , biological cells may have compromised function.
