Hello students, in this question, the concentration of the acetic acid and sodium hydroxide is given and the dissociation constant of the acetic acid is given.
00:10
We have to titrate acetic acid and naoh and we have to find the suitable indicator for this titration process.
00:17
First of all we want to know that acetic acid is a weak acid.
00:21
Therefore, it partially dissociate into acetate ion that is ch3coo - plus h plus ion.
00:31
Here the concentration of the h plus ion is comparatively less.
00:35
Therefore, the ph of the solution will be greater than 6.
00:39
Next we are going to titrate it against naoh.
00:42
Sodium hydroxide is a strong base, therefore it dissociate completely into na plus and oh minus ions.
00:51
The concentration of the oh minus ion is comparatively higher, therefore it will increase the ph further.
00:59
And the equivalence point for this reaction will be reached at the ph greater than 8...
