CH3COOH is titrated in the NaOH solution...

`CH_3COOH` is titrated in the NaOH solution which of the following statements is correct for such titration?

A

Conductance increases upto equivalence point, then it decreases.

B

Conductance decreases upto equivalence point, then it increases.

C

First conductance increases slowly upto equivalence point and then increases rapidly.

D

Before the equivalent point, there exists buffer solution.

Text Solution

Verified by Experts

The correct Answer is:
C, D
`CH_3COOH " Vs " NaOH`
`CH_3COOH ` weak acid ( dissociated less extent )
NaOH is strong Base ( dissociate large extent )
`CH_3COOH + NaOH to Ch_3COONa + H_2O`
`CH_3COOH + CH_3COONa` acidic buffer
`:.` E.M.F conductance increases slowly upto equivalence point and then increases rapidly . Therefore equivalence point there exist is acidic buffer
