To calculate the pH of a buffer solution, the Henderson-Hasselbalch equation is used, pH = pka + log(acid/base). If working with a weak acid and conjugate base, the pka is found and plugged into the concentrations for each added to the solution.What...

The invention includes a method for the optimization of the soluble CO2 concentration in the aeration basin of an activated sludge system, which significantly improves the specific growth rate of the nitrifying bacteria. The result is a reduction in capital and energy costs for municipalities. The ...
Formation of the Hydrogen IonpH describes how acidic or basic a solution is. Whether an aqueous solution reacts as an acid or a base depends on its hydrogen ion (H+) content. In fact, the term "pH" originates from Latin and is an acronym for "potentia hydrogenii" - the power of ...
Results show that the polymers have excellent stability in solution with low critical micelle concentration (CMC) (0.0025–0.0034 mg/mL) and the apparent base dissociation constant (pKb) of the polymers is from 5.31 to 6.05. Dynamic light scattering analysis exhibits the great environmental response...
Measurement of hydrogen in non-aqueous solvents can be conducted with electrodes that contain a non-aqueous filling solution (i.e., saturated lithium chloride in ethanol for non-polar solvents or acetic acid for polar solvents). 2.2. Acid—Base ReactionsThe transfer of hydrogen ions in an acid...
If you’re using very soft water then you will need just a tiny amount of fluid to adjust the water’s pH since there’s not much “stuff” in the water to buffer the pH. However, if you’re using hard water then you’ll need to add more. For PH Down –1 mL/gallon of water...
