Borate buffer calculator
WebApr 13, 2024 · A borate buffer system works slightly different than a bicarbonate buffer, which is used up at lower pH, where the carbonic acid forms dissolved CO2, which is lost by evaporating out of the water, thereby losing part of the buffer. ... just like the CYA adjustment factor, for calculating the CA. Though, the borate correction factor is … WebFor a buffer with pH 9.3 you must calculate that the buffer must contain H3BO3 and H2BO3-As a quick question : —-What would be the buffer pH if it was produced from 0.5 M H3BO3 and 0.5 M NaH2BO3? ... You want a borate buffer , pH = 9.3 . Boric acid is H3BO3 . The acid has three stages of dissociation. H3BO3 ↔ H+ + H2BO3 - pKa 9.24.
