Question

A+ B titrations can be performed with different combos of strong + weak acids and bases but are most useful when using a combo that involves:

Answer 1

To choose the appropriate acid-base indicator for the titration of a weak base with a strong acid, consider the pH at the equivalence point.

Step-by-step explanation:

When performing titrations of weak bases with strong acids, it is important to choose the appropriate acid-base indicator. For a weak base, the pH at the equivalence point is less than 7.0. Therefore, an indicator such as methyl red or bromocresol blue, with pKa < 7.0, should be used. This is because these indicators change color within the pH range of the titration.
