In which of the following acid-base titration, the pH is greater than 8 at the equivalence point ?

A

Acetic acid versus ammonia

B

Acetic acid versus sodium hydroxide

C

Hydrochloric acid versus ammonia

D

Hydrochloric acid versus sodium hydroxide

Text Solution

Verified by Experts

The correct Answer is:
B
Acetic acid is a weak acid while sodium hydroxide is a strong base. Therefore at the equivalent point, there will be enough hydroxide ions left.

Which of the following are true for an acid- base titration?

A weak acid is titrated with a weak base. Consider the following statmenets regarding the pH of the solution at the equivalence point : (i) pH depends on the concentration of acid and base. (ii) pH is independent of the concentration of acid and base. (iii) pH depends on the pK_a of acid and pK_b of base. (iv) pH is independent of the pK_a of acid and pK_b of base. The correct statments are :

acid base titration,iodometric titration

10 mL of H_(2)A (weak diprtic acid) solutio is titrated against 0.1M NaOH. pH of the solution is plotted against volume of strong base added and following obserbation is made Ip pH of the solution at first equivalence point is pH_(1) and at secnd equibalence point is pH_(2^.) Calculate the value of (pH_(2)-pH_(1)) at 25^(@)C Given for H_(2)A,pK_(a_1) =4.6 and pK_(a_2) =8, log 25=1.4
