WebThe working ranges of Kb values go from 10 (very mild) to 200 or even higher (very strong cleaning). For years, the Kb value has been used to judge the relative cleaning “power” of cleaning fluids used on electronics, metals, optics and elsewhere. The Kb value is usually reported on MicroCare product spec sheets as “Kb value.”. WebWhat is the effect on the concentrations of NO2−, HNO2, and OH− when the following are added to a solution of KNO2 in water: (a) HCl (b) HNO2 (c) NaOH (d) NaCl (e) KNO The equation for the equilibrium is: NO2− (aq)+H2O (l) ⇌ HNO2 (aq)+OH− (aq)

The thermal voltage is also important in plasmas and electrolyte solutions (e.g. the Nernst equation ); in both cases it provides a measure of how much the spatial distribution of electrons or ions is affected by a boundary held at a fixed voltage. WebFeb 4, 2024 · Ka, pKa, Kb, and pKb are most helpful when predicting whether a species will donate or accept protons at a specific pH value. They describe the degree of ionization of an acid or base and are true indicators of acid or base strength because adding water to a solution will not change the equilibrium constant. Ka and pKa relate to acids, while Kb ... mama\\u0027s window lynn rubright story
