It becomes viable to see all three endpoints if phosphoric acid is titrated, as seen in Fig. 5. Figure 5. Exothermic titration curve of phosphoric acid titrated with NaOH. Here, all three ...

If phosphoric acid is titrated, it is possible to observe all three endpoints (Fig. 5). Figure 5. Exothermic titration curve of phosphoric acid titrated with NaOH. Here, all three deprotonation steps ...
