Phenolphthalein Manufacturer,Supplier and Exporter in India
Product Code : EL-CL-12326
Jlab Export is a leading Phenolphthalein Manufacturer,and suppliers in India
Phenolphthalein (code EL-CL-12326) is the acid-base indicator that stays colourless in acidic and neutral solutions and turns pink between about pH 8.2 and 10. Because the change falls on the alkaline side, it is chosen for titrations with a strong base such as sodium hydroxide. JLab prepares it in Ambala, India, as one of its own indicators.

Titrations That Suit Phenolphthalein
For a strong acid against sodium hydroxide, or a weak acid such as ethanoic or oxalic acid against the same alkali, the equivalence point lies at or above neutral, so the first permanent pink marks the end. When a weak base such as ammonia is titrated with an acid, the equivalence point is acidic and the pink would vanish too early; methyl orange is used there instead.
Related Titration Reagents
- Sodium Hydroxide — the strong base titrated with this indicator.
- Oxalic Acid — primary standard acid titrated against alkali with phenolphthalein.
- Methyl Orange — the indicator for strong acid against weak base titrations.
- Phenolphthalein — a smaller bottle of the same indicator in the Biology Lab range.
More acid-base indicators are stocked in Chemistry Lab.
