Phenolphthalein (1% in 60% Ethanol) -500ml

Phenolphthalein (1% in 60% Ethanol) is a classic acid-base indicator solution prepared in a 60% ethanol medium for enhanced solubility and stability. It is widely used in acid-base titrations, turning colorless in acidic conditions and pink to red in alkaline solutions (pH range 8.2–10.0).

Uses:

• Indicator in acid-base titrations for determining endpoints

• pH testing in analytical and educational laboratories

• Standard reagent in water, food, and chemical analysis

• Useful in demonstration experiments to visualize pH changes

Key Features:

• Concentration: 1% phenolphthalein in 60% ethanol

• Distinct color transition: Colorless → Pink at pH 8.2–10.0

• High solubility and long shelf-life due to ethanol base

• Ready-to-use laboratory-grade solution

• Reliable performance for accurate titration results

Safety / Handling:

• Flammable – contains ethanol; keep away from open flames and heat sources

• Avoid contact with skin and eyes; use protective gloves and eyewear

• Store tightly closed in a cool, dry, well-ventilated place

• Dispose of according to local hazardous waste regulations
