Re: [APD] How to make a good KH reference stock solution for CO2

There isn't anything that is commercially available that we could use? I mean do the pH calibration packets we use have an accurate KH?

"Formulation Hanna pH buffers are made of Potassium Dihydrogen Phosphate and Disodium Hydrogen Phosphate and are standardized with a pH meter that is calibrated to NIST primary standard buffer solutions (NIST 186Ie & 186IIe and NIST 158g S.R.M.). "
