Question

At the equivalence point for a weak acid-strong base titration an equal number of moles of OH- and H have reacted, producing a solution of water and salt. What affects the pH at the equivalence point for a weak-acid/strong-base titration

Answer 1

Answer:

The pH shifts less with small additions of titrant near the equivalence point.

Explanation:

Answer 2

Explanation:

In an acid-base titration, the titration curve reflects the strengths of the corresponding acid and base.

If one reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular, and the pH shifts less with small additions of titrant near the equivalence point.

Acid-base titrations depend on the neutralization between an acid and a base when mixed in solution.

The endpoint and the equivalence point are not exactly the same: the equivalence point is determined by the stoichiometry of the reaction, while the endpoint is just the color change from the indicator.
