Ammonia Buffer Solution 500ML , Packaging Detai

Product Description

• Composition: An ammonia buffer solution is created by combining a weak base (ammonia, NH3) with one of its salts (ammonium chloride, NH4Cl).
• pH Range: These buffers typically maintain a pH in the alkaline range, specifically around 10-11.
• Purpose:
  • EDTA Titrations: They are frequently used in EDTA (ethylenediaminetetraacetic acid) titrations to ensure the sample pH remains at 10, which is crucial for specific reactions and color changes at the endpoint.
  • pH Calibration: They can be used for establishing and maintaining hydrogen ion activity, which is important for calibrating pH meters and in analytical procedures.
  • Maintaining Stability: They help maintain the stability of various dosage forms.
  • Complexometric Titration: They can be used in complexometric titration.
• Appearance: Ammonia buffer solutions are typically clear, colorless liquids with a strong ammoniacal odor.
• Safety: They are corrosive and can cause severe skin burns and eye damage, so appropriate safety precautions should be taken.
• Preparation:
  • pH 10.0: Dissolve 5.4 g of ammonium chloride in 20 ml of water, add 35 ml of 10 M ammonia, and dilute with water to 100 ml.
  • pH 10.9: Dissolve 67.5 g of ammonium chloride in sufficient 10 M ammonia to produce 1000 m
