Description

Description générale

Arsenic(III) oxide is a volumetric standard produced under rigorous conditions and measured with the highest possible precision. Its content determination and homogeneity assessment are carried out using volumetric redox titration as the primary analysis method.

This compound is listed in the SVHC (Substances of very high concern) candidate list of ECHA (European Chemicals Agency)

Application

The reference material is to be used as a reductometric standard for titer determinations in redox titrations.

Caractéristiques et avantages
