WebJun 17, 2024 · 1 Answer. Sorted by: 11. H X 2 S O X 4 is one of common strong acids, meaning that K X a ( 1) is large and that its dissociation even in moderately concentrated aqueous solutions is almost complete. Arrhenius dissociation: H X 2 S O X 4 ↽ − − ⇀ H X + + H S O X 4 X − K X a ( 1) = l a r g e. Brønsted-Lowry Dissociation: WebNov 21, 2024 · S14.7.1. At the equivalence point in the titration of a weak base with a strong acid, the resulting solution is slightly acidic due to the presence of the conjugate acid. Thus, pick an indicator that changes color in the acidic range and brackets the pH at the equivalence point. Methyl orange is a good example.
