(A) In general phenolphthalein is used as an indicator for the titration of weak acid `(CH_(3)COOH)` and strong base (NaOH).
(R) At equivalence point solution is basic.

Which indicator is suitable for the titration of a weak acid with strong base -

In the titration of weak acid against strong base, at the half equivalence point (half-neutralization) :

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

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

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

Explain why phenolphthalein is used as an indicator in acid-base titration. ""^(**"**)

(a). IF both (A) and (R) are correct and (R) is the correct explanation of (A). (b). If both (A) and (R) are correct but (R) is not the correct explanation of (A). (c). If (A) is correct, but (R) is incorrect. (d). If (A) is incorrect, but (R) is correct. ltbr. (e) if both (A) and (R) are incorrect. Q. Assertion (A): In the titration of strong acid and strong base, phenolphthalein is used as suitable indocator. Reason (R): IN the titration of strong acid and strong base, the equivalence points lies is the pH range of (3.0-10.5) and phenolphthalein have pH range of (8.0-9.8) .
