1 ml = 0,01176 g K2Cr2O7 This volumetric solution was checked by means of volumetric methods using an ammonium iron(II) sulfate standard solution, that was also checked against Scharlau’s potassium dichromate volumetric standard. Scharlau’s volumetric standards are directly traceable to the Standard Reference Materials from NIST (National Institute of Standards and Technology, USA).
