Equilibrium: NEET 2026

Easy· Acid - Base Titration (Titration Curves for Weak Acid Vs Strong Base)· +4 / −1
Phenolphthalein is used as an indicator for the titration of sodium hydroxide solution against a standard solution of oxalic acid. The colour change that is observed at an alkaline pH close to the equivalence point during this titration is:
