Question

Titration (c) Titration (d) 14 12 10 10 100 200 0 100 200 30000 Volume of titrent, ml Volume of titr ant, ml 44. Which one of the titration curves corresponds to the titration of a weak acid (in flask) wth strong base (in buret)? B. a C. b C. c D. d 45. Consider titration curve (d). Which one of the following best characterizes the solution in the flask at the equivalence point of the titration? (a) a solution of a strong acid (b) a solution of a strong base (c) a solution of a weak acid (d) a solution of a weak base (e) a neutral solution

Explanation / Answer

44 ) c is the answer  the  reagent is a weak acid or base and the other is a strong acid or base, the titration curve is irregular, and the pH shifts less with small additions of titrant near the equivalence point. Acid-base titrationsdepend on the neutralization between an acid and abase when mixed in solution.

45 ) c solution of weak acid is there in the flask when it reaches to equivalence point of titration.
