When dissolved in water, it first gives up one proton and dissociates to dihydrogen phosphate, i.e. it reacts like a monoprotic acid (see formula 1). The addition of sodium hydroxide, e.g. during titration, first leads to complete dissociation of the phosphoric acid into dihydrogen phosphate.

WebIn order for the titration to reveal that point, the pH of the base used would need to far exceed the value of the third p Ka . The third p Ka value for phosphoric acid is 12.4. The base used in the titration would have to exceed this value by about 2 pH units to produce the third equivalence point. WebJan 29, 2024 · You can add a single dose of NaOH to a sample of the acid and measure the pH with the pH meter.
