Answer 2

Option D) is a false statement, It must be slow & quantitative​ is not a true statement.

Explanation:

A) It must be rapid & quantitative is a correct statement as the titration forms precipitate and it all happens rapidly.

B) It must give insoluble precipitates at the endpoint This is a correct statement because at the endpoint it should give an insoluble precipitate to show the visible difference.

C) It must not be affected by co-precipitation/post precipitation. In the titration, coprecipitation and post precipitation should not affect the titration.

D) It must be slow & quantitative​. This is not a correct statement as the reaction should be quantitative but should be rapid.
