FAQs
1. What is Phenolphthalein 2% Solution primarily used for?
Phenolphthalein 2% Solution is primarily used as an acid-base indicator in titrations and other chemical analyses where a clear visual pH change is required.
2. What color changes does Phenolphthalein indicator display?
Phenolphthalein is colorless in acidic solutions and turns pink or magenta in basic solutions, typically above a pH of 8.2.
3. How should this Phenolphthalein solution be stored to maintain its efficacy?
It should be stored in a cool, dry place, away from direct sunlight and heat, in its original tightly sealed container to prevent evaporation and contamination.
4. Can this Phenolphthalein solution be used for all types of titrations?
It is best suited for titrations involving a strong acid and a strong base, or a weak acid and a strong base, where the equivalence point falls within its pH transition range (8.2-10.0).
5. Is the 2% concentration suitable for general laboratory experiments?
Yes, the 2% concentration is a standard and highly effective formulation for most general laboratory experiments, offering clear and precise indicator performance.
