WebThe pH is determined from the Henderson-Hasselbach equation: pH = pKa + log ( [A−]/ [HA]).Solution: Since the molarities of the two solutions making the buffer are the same, the Henderson-Hasselbach equation can be written as: pH = pKa + log (V (A−)/V (HA)) where V (A−) = the volume of the conjugate base and V (HA) = the volume of the conjugate … WebInitial pH of acid b.)

Oxalic acid's pKa values vary in the literature from 1.25–1.46 and 3.81–4.40. The 100th ed of the CRC, released in 2024, has values of 1.25 and 3.81. Oxalic acid is relatively strong compared to other carboxylic acids: Oxalic acid undergoes many of the reactions characteristic of other carboxylic acids. It forms esters such as dimethyl oxalate (m.p. 52.5 to 53.5 °C, 126.5 to 128.3 °F). It forms an acid chloride …
