During titration of acetic acid with aq....

During titration of acetic acid with aq. NaOH solution, the neutralisation graph has a vertical line. This line indicates

A

alkaline nature of equivalence

B

acidic nature of equivalence

C

neutral nature of equivalence

D

depends on experimental proceeding.

Text Solution

Verified by Experts

The correct Answer is:
A
In any type of acid-base titration, there is a sudden change in the pH value at the end point. During the titration of weak acid with a strong base, beyond the equivalent point, the solution will contain the salt and excess of free base.
`CH_(3)COOH+NaOH rarr underset("Sodium acetate")(CH_(3)COONa)+H_(2)O`
Due to the presence of free base, solution becomes alkaline in nature.
