A 200.0-mL sample of the weak acid H 3 A (0.100 M) is titrated with 0.200 M NaOH. What are the major species at each of the following points in the titration? (Water is always assumed to be a major species.)
-After 350.0 mL of 0.200 M NaOH is added

After adding 350.0 mL of 0.200 M NaOH to 200.0 mL of 0.100 M weak acid, the solution is beyond the equivalence point. The major species are OH⁻ from the excess NaOH and A³⁻, the fully deprotonated form of the acid.
