Phenolphthalein Indicator w/ Dropper Bottle

Description

Phenolphthalein 1% Solution is a high-quality, laboratory-grade indicator designed for accurate acid-base titrations and pH testing. With a reliable pH transition range (colorless to pink between pH 8.2–10.0), this ready-to-use solution is essential for precise measurements in both educational and professional settings. Commonly used in chemistry labs, industrial quality control, and even forensic applications, phenolphthalein is a versatile and indispensable tool.

Applications:

Laboratory Applications

• Acid-Base Titration:
  • Phenolphthalein is commonly used to determine the endpoint in titrations. It is colorless in acidic solutions and turns pink in basic solutions, with a transition range of pH 8.2 to 10.0.
• pH Indicator:
  • Used to measure pH in experiments where a distinct color change is needed.

Industrial Applications

• Quality Control:
  • Used in industrial processes like manufacturing soaps, detergents, and other alkaline products to monitor pH levels.
• Dye Manufacturing:
  • A precursor or additive in producing certain synthetic dyes.

Medical Applications

• Laxatives (Historical Use):
  • Once used in over-the-counter laxatives due to its effect on the digestive system. However, its use has declined due to safety concerns.

Educational Uses

• Demonstrations:
  • Frequently employed in chemistry education to visually illustrate the principles of acid-base reactions and pH changes.

Forensic Applications

• Latent Blood Detection:
  • Phenolphthalein is used in the Kastle-Meyer test for detecting traces of blood. It reacts with hemoglobin to produce a pink color in the presence of hydrogen peroxide.

Environmental Testing

• Water Analysis:
  • Used to test the alkalinity of water samples and assess environmental conditions.

Art and Conservation

• Art Restoration:
  • Occasionally used to neutralize acidity in paper and other materials to preserve artifacts.

DIY and Creative Applications

• Invisible Ink:
  • Phenolphthalein can be used as a component in invisible ink that appears when treated with a basic solution.
