Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Phenolphthalein is a suitable indicator for the titration of a strong base (sodium hydroxide) against a weak acid (oxalic acid). The end point is indicated by a colour change from colourless in acidic solution to pink in basic solution.

Questions Asked in NEET exam
- Given below are two statements: one is labelled as Assertion A and the other is labelled as Reason R.
Assertion A : The potential (V) at any axial point, at 2 m distance(r) from the centre of the dipole of dipole moment vector \(\vec{P}\) of magnitude, 4 × 10-6 C m, is ± 9 × 103 V.
(Take \(\frac{1}{4\pi\epsilon_0}=9\times10^9\) SI units)
Reason R : \(V=±\frac{2P}{4\pi \epsilon_0r^2}\), where r is the distance of any axial point, situated at 2 m from the centre of the dipole.
