8 cze 2024 · The pH of a solution of oxalic acid in water is determined by the acid dissociation constants (pKa) of oxalic acid. Oxalic acid is a polyprotic acid, which means it can donate more than one proton (H+) in solution.

solution of oxalic acid will be titrated with NaOH to the end-point and beyond. A graph of pH versus volume of NaOH will be plotted and the concentration of the NaOH solution will be calculated. Purpose: The purpose of this experiment is to titrate an NaOH solution to find its concentration. Equipment / Materials: pH meter oxalic acid
A student dissolved a 0.139 g sample of oxalic acid, H2C20 4, in water in an Erlenmeyer lask. Then the student titrated the H2C204 solution in the lask with a solution of KMn04, which has a dark purple color. The balanced chemical equation for the reaction that occurred during the titration is shown above.
Adding sodium hydroxide solution to dilute ethanedioic acid. Ethanedioic acid was previously known as oxalic acid. It is a diprotic acid, which means that it can give away 2 protons (hydrogen ions) to a base. Something which can only give away one (like HCl) is known as a monoprotic acid.
