WebH 3 O + concentration given by water is neglected because dissociation of water is much lower compared to the formic acid dissociation. Because H 3 O + concentration is known now, pH value of formic acid solution can be calculated. pH = -log [H 3 O +(aq)] pH = -log [4.24 * 10 -3] pH = 2.37 pH Calculator of aqueous formic acid solution WebApr 26, 2024 · The addition of 100 milliequivalent/liter hydrochloric acid to normal saline produced a pH of approximately 1.5, whereas, addition of the same amount to a 3.5%, 5.5%, and 8.5% amino acid solution increased the pH to approximately 3, 4.5, and 5, respectively.
