1 ml = 0,009718 g KSCN This volumetric solution was checked by means of potentiometric methods using a silver nitrate standard solution, that was also checked against Scharlau’s potassium chloride volumetric standard. Scharlau’s volumetric standards are directly traceable to the Standard Reference Materials from NIST (National Institute of Standards and Technology, USA).
