Question

The following titration curve is most likely to be associated with a. the titration of a strong acid with a strong base titrant. b. the titration of a weak acid with a strong base titrant. c. the titration of a strong base with a strong acid titrant. d. the titration of a weak base with a strong acid titrant. What is indicated by the shape of the titration curve? a. A diprotic acid was titrated with a strong base. b. A triprotic acid was titrated with a strong base. c. A diprotic base was titrated with a strong acid. d. A triprotic base was titrated with a strong acid. e. A strong acid was titrated with a strong base.

Explanation / Answer

(14) There is increment in the pH indicationg that an acid is being titrated with a base.

And there is no sharp change in pH at the end point the acid being titrated is weak.

So, The curve represents, (b) titration of a weak acid with strong base titrant

(15) SInce the pH is being decreased, it indicates the titration of a base with an acid.

Since there are three minima, it is triprotic acid.

So, (d) A triprotic acid was titrated with a strong acid.
