WebAug 3, 2012 · The nominal pyridine 2,4,6-tricarboxylic acid (H 3 ptc) starting material was prepared by oxidizing 2,4,6-trimethyl pyridine with KMnO 4 solution, as described by Syper et al. . This evidently generated a potassium salt: A 0.5-mmol solution was prepared by heating 0.11 g of the solid product in 10.0 mL water in a 50-mL round bottom flask. WebOrdinarily, the pH of a solution varies between 0 and 14, and the solutions with the pH values lower than 7 are called acidic, while those of a pH value higher than 7 are called alkaline. The pH of a solution can be calculated if the amount of acid or base added to a formed solution is known (therefore the equilibrium between H1 and OH2 is known).
