Description

Descripción general

Sodium chloride (NaCl) is a volumetric standard manufactured under rigorous conditions and analyzed with the highest possible precision. The content of the standard is measured by volumetric argentometric titration and the measurement can be traced back to NIST SRM. Its certified value and uncertainty measurement are in accordance with ISO Guide 35.

Aplicación

It finds its use as a certified reference material (CRM) for the standardization of volumetric solutions in argentometric titrations.
