Meets AP® Chemistry topics 6, 7, and 10. Teach students the relationship between mass, moles, and stoichiometry while helping them build strong data analysis skills. Students standardize a solution of sodium hydroxide and use it to titrate a solution of an unknown polyprotic acid. They then plot a titration curve and use it to determine the first 2 acid dissociation constants and molecular weight of the unknown acid.

Meets AP® Chemistry topics 6, 7, and 10. Teach students the relationship between mass, moles, and stoichiometry while helping them build strong data analysis skills. Students standardize a solution of sodium hydroxide and use it to titrate a solution of an unknown polyprotic acid. They then plot a titration curve and use it to determine the first 2 acid dissociation constants and molecular weight of the unknown acid.

From their analysis, students identify the unknown acid from a list of polyprotic acids. Materials are sufficient for 30 students working in pairs. Materials needed, but not supplied, include pH sensors and probeware.
