Vedclass · Answer

(D) In the titration of a weak acid and a strong base,the $pH$ at the equivalence point is greater than $7$ (typically between $8$ and $10$).Phenolphthalein is the most suitable indicator because its $pH$ range ($8.2$ to $10$) coincides with the $pH$ change at the equivalence point of this titration.Methyl orange and Methyl red are suitable for strong acid-strong base or strong acid-weak base titrations,as their $pH$ ranges are in the acidic region.

The best indicator for the detection of the end point in the titration of a weak acid and a strong base is:
