Phenolphthalein Indicator w/ Dropper Bottle – Lab Grade

Description

Phenolphthalein is a widely used chemical indicator known for its distinct color change, making it an essential tool in analytical chemistry and laboratory applications. It is primarily used to determine the endpoint in acid-base titrations due to its sharp color transition.

Applications of Phenolphthalein Indicator

Acid-Base Titrations

• Used extensively as an endpoint indicator in acid-base titration experiments.
• Changes color from colorless (acidic) to pink/magenta (basic) within a pH range of 8.2 to 10.0, allowing precise detection of neutralization.

Laboratory Analysis

• Educational Use: A staple in teaching laboratories for demonstrating pH changes and titration techniques.
• Research Applications: Employed in chemical analysis for experiments involving acidity or alkalinity.

Industrial Applications

• Water Testing: Utilized to measure the alkalinity or acidity in water treatment processes.
• Soil Analysis: Helps determine the pH of soil samples for agricultural and environmental studies.
• Chemical Manufacturing: Used in quality control processes to monitor pH levels during production.

Environmental Studies

• Applied in environmental monitoring to analyze the pH of natural water bodies and assess pollution levels.

Forensic Science

• In combination with hydrogen peroxide, phenolphthalein is used in presumptive tests for detecting bloodstains. The reaction produces a characteristic pink color in the presence of hemoglobin.

Pharmaceutical Industry

• Historically used as a laxative ingredient (now less common due to regulatory changes and potential health risks).

Art and Craft

• Occasionally used in artistic projects and experiments for creating pH-sensitive color-changing effects.

Green Chemistry and Innovations

• Investigated in modern research for innovative applications in pH-sensitive materials and sensors.

Storage Guidelines

• Temperature:
  • Store in a cool, dry place with a temperature range of 15°C to 25°C (59°F to 77°F).
  • Avoid extreme heat or freezing conditions.
• Containers:
  • Keep in a tightly sealed, labeled container to prevent contamination.
  • Use containers made of glass or chemically resistant plastic.
• Environment:
  • Protect from moisture and direct sunlight, as these can degrade the compound over time.
  • Store away from incompatible substances like strong acids, bases, and oxidizing agents.
• Shelf Life:
  • Phenolphthalein typically has a long shelf life when stored under proper conditions. Check packaging for specific expiration dates.

Handling Guidelines

• Personal Protective Equipment (PPE):
  • Wear appropriate PPE, including:
    • Gloves: Chemical-resistant gloves to prevent skin contact.
    • Eye Protection: Safety goggles or a face shield.
    • Clothing: Lab coat or long-sleeved protective clothing.
• Work Area:
  • Handle in a well-ventilated area or under a fume hood to minimize inhalation of dust or vapors.
  • Ensure the work area is free of food, drinks, and other non-laboratory items.
• Precautions:
  • Avoid ingestion, inhalation, and contact with skin or eyes.
  • Wash hands thoroughly after handling, even if gloves are used.
• First Aid Measures:
  • Inhalation: Move to fresh air immediately. Seek medical attention if symptoms persist.
  • Skin Contact: Wash with soap and water. Remove contaminated clothing.
  • Eye Contact: Rinse with water for at least 15 minutes. Seek medical attention if irritation continues.
  • Ingestion: Do not induce vomiting. Rinse mouth and seek medical attention immediately.

Disposal

• Dispose of Phenolphthalein according to local, regional, and national regulations.
• Avoid releasing into the environment; use a licensed chemical waste disposal service if necessary.
