H-2 Hardness (Total) Buffer
H-2 Hardness (Total) Buffer is a specialized reagent used in complexometric titration for determining total water hardness. It provides the required alkaline conditions (commonly with ammonia/ammonium chloride buffer) to stabilize calcium and magnesium ions during titration with hardness titrants such as EDTA.
Appearance
-
Clear liquid solution
-
Typically colorless to light yellow


Uses
-
Water hardness analysis: ensures correct pH (~10) for accurate complexation of Ca²⁺ and Mg²⁺ with EDTA
-
Laboratory testing in water treatment plants, industrial facilities, and environmental labs
-
Quality control: works in combination with hardness titrants and indicators (e.g., Eriochrome Black T)
Key Features
-
Pre-formulated buffer for consistent results
-
Maintains stable alkaline conditions during titration
-
Enhances accuracy of calcium and magnesium ion determination
-
Easy-to-use reagent for both field and laboratory settings
SDS (Safety Data Highlights)
-
Hazards: Irritant to skin, eyes, and respiratory tract; may be harmful if swallowed
-
Precautions: Use gloves, goggles, and lab coat; ensure good ventilation
-
Storage: Keep container tightly closed in a cool, dry, well-ventilated area
-
First Aid:
-
Eyes: Rinse thoroughly with water
-
Skin: Wash with soap and water
-
Ingestion: Rinse mouth, seek medical advice
