WebApr 20, 2024 · Or in logarithimic form: pH = pK1 + log( [HX2COX3] [HCO3 −]) As we know the pH and K1, we can calculate the ratio between carbonic acid and bicarbonate. If you want to study in depth such calculations, I recommend this book: Butler, James N. Ionic Equilibrium: Solubility and PH Calculations. John Wiley & Sons, 1998.

WebThe optimum pH for Nitrosomonasand Nitrobacteris between 7.5 and 8.5; most treatment plants are able to effectively nitrify with a pH of 6.5 to 7.0. Nitrification stops at a pH below 6.0. The nitrificaiton reaction (that is, the conversion of ammonia to nitrate) consumes 7.1 mg/L of alkalinity as CaCO3for each mg/L of ammonia nitrogen oxidized. terminal c section
