Question

Which statement about this titration curve is true? a) this is a titration of a weak acid with strong base b) the pH at the equivalence point is 7.0 c) at 8 mL of titrant added, the resulting mixture is a buffer. 1 Use this titration curve to answer the next two questions. 10 13. Which statement about this titration curve is true? This is a titration of a weak acid with strong base. a. b. The pH at the equivalence point is 7.0. c. At 8 ml of titrant added, the resulting mixture is a buffer. At 10 mL of titrant added, the pH equals the pKb of the base. d. 10 15 vol titrant added Im 20 25 S0

Explanation / Answer

a is incorrect because it is a titration curve of strong acid weak base.

b is incorrect because at equivalance point pH is 4.4

Option c is correct because there is very little change in pH with adition of acid.

Option d is incorrect at equivalace point pH =pKa and equivalance point is at 20 ml of titrant added.
