Titriplex^® III solution

for 1000 ml, c(Na₂-EDTA 2 H₂O) = 0.01 mol/l Titrisol^®

Concentration after dilution to 1 liter: c(C₁₀H₁₄N₂Na₂O₈ ∙ 2 H₂O) = 0.01 mol/lAmount-of-substance concentration0.01000 mol/lThe concentration of this solution was determined with volumetric standard zinc (article number 1.02409). The determined titer at 20°C was 1.000 with an expanded measurement uncertainty of ± 0.004 (k=2 coverage factor for 95% coverage probability). The certified value is traceable to primary standard NIST SRM 682 (NIST: National Institute of Standards and Technology, USA) by means of volumetric standard zinc, measured in the accredited calibration laboratory of Merck KGaA, Darmstadt, Germany in accordance to DIN EN ISO/IEC 17025.
