pH at 20 °C………………………………………………………. 3,00

uncertainty ± 0,01

Composition per litre is 0,7ml ortho- Phosphoric acid concentrated and 11,2g Potassium dihydrogen phosphate. Standard buffer solutions are prepared using gravimetric and volumetric procedures. The batch value is determined by measurement with a combination glass electrode against five-point calibration according to DIN 19268. This pH buffer solution is traceable to Standard Reference Material from NIST.
