Question

which statements about titration curves are correct? select all that apply: the ph at the equivalence point of the titration of a strong acid with a strong base is 7.00. the ph at the equivalence point of the titration of a weak acid with a strong base is greater than 7.00. past the equivalence point, the ph increases rapidly, since there is excess hydroxide added. the starting ph of a weak acid titrated with a strong base is lower than the starting ph of a strong acid titrated with a strong base.

Answer 1

The pH at the equivalence point of a titration depends on the type of acid and base being used. In the titration of a strong acid with a strong base, the pH at the equivalence point is 7.00. However, in the titration of a weak acid with a strong base, the pH at the equivalence point is greater than 7.00. Past the equivalence point, the pH increases rapidly due to the excess hydroxide added. The starting pH of a weak acid titrated with a strong base is lower than the starting pH of a strong acid titrated with a strong base.

Step-by-step explanation:

A titration curve is a graphical representation of the pH changes that occur during a titration. In the titration of a strong acid with a strong base, the pH at the equivalence point is 7.00. However, in the titration of a weak acid with a strong base, the pH at the equivalence point is greater than 7.00. Additionally, past the equivalence point, the pH increases rapidly due to the excess hydroxide added. Finally, the starting pH of a weak acid titrated with a strong base is lower than the starting pH of a strong acid titrated with a strong base.
