Specifications
pH at 20 °C…………………………………………..10,00
uncertainty ± 0,02
Composition per litre is 2,64g Sodium carbonate and 2,09g Sodium hydrogen carbonate. Standard buffer solutions are prepared using gravimetric and volumetric procedures. The batch value is determined by measurement with a combination glass electrode against two-point calibration according to DIN 19268. This pH buffer solution is traceable to Standard Reference Material from NIST.
