In which of the following titrations would the solution be neutral at the equivalence point? [Hint: For a neutral equivalence point, we need both a strong acid and a strong base as analyte and titrant, respectively.] HOCl titrated with Ba(OH)2 CH3COOH titrated with NaOH HClO4 titrated with KOH Sr(OH)2 titrated with H3PO4 NH3 titrated with HCl

Which of the following conditions is/are met at the equivalence point of the titration of a monoprotic weak base with a strong acid? 1. The moles of acid added from the buret equals the initial moles of weak base. 2. The volume of acid added from the buret must equal the volume of base titrated. 3. The pH of the solution is less than 7.00.

Part A The volume required to reach the equivalence point of an acid-base litration depends on the volume and concentration of the acid or base to be titrated and on the concentration of the acid or base used to do the titration. It does not, however, depend on the whether or not the acid or base being litrated is strong or weak. Explain Match the words in the left column to the appropriate blanks in the sentences on the right...

The half‑equivalence point of a titration occurs half way to the
equivalence point, where half of the analyze has reacted to form
its conjugate, and the other half still remains unreacted.
