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
