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

Options

A. Methy1 orange `(pH` range `3 to 4)`
B. Methy1 red `(pH` range `4 to 6)`
C. Thymol blue `(pH` range `8 to 3)`
D. Phemolphethalein `(pH` range `8 to 10)`

Answer

Explanation

Indicator used for the titration of `WA` and `SB` is phenolphtaleim. Since the `pH` range near the end point is `8` to `10`.
