Innovating Science® - Titration of Polyprotic Acids

Product # IS6505

Because of successive dissociations, titration curves of polyprotic acids have multiple equivalence points. By creating a graph of the titration curve (pH vs. volume of NaOH) an unknown acid can be identified.

Aligned to the Next Generation Science Standards (NGSS)*

Disciplinary Core Ideas: PS1.A; PS1.B
Performance Expectations: MS-PS1-2
Cross Cutting Concepts: Structure and Function
Engineering Practices: Developing and Using Models
