The higher the Ka and Kb values, the weaker the acid or base. When Ka values equal Kb values, the acid is strong. Ka and Kb values do not provide information about acid and base strength.Create your account to access this entire worksheet A Premium account gives you access to all lesson...
the lower the ka value, the higher the pka value, and the weaker the acid. predict equilibrium and strength of acids using ka and pka ka can be used to calculate the equilibrium position: when ka is big, the creation of dissociation products is encouraged. when ka is low, the un...
pH, Ka, andpKaare all related to each other. For an acid HA: Ka= [H+][A-] / [HA] pKa= - log Ka pH = - log([H+]) At the halfway point on an equivalence curve, pH = pKa. Ka of Weak Acids Ka of Weak Acids NameFormulaKapKa ...

For as many times as I’ve introduced old laptops on this blog, you’d think I’d have a formula or a template page tucked away somewhere. But I don’t, and here we are again with another underdog to report. I hope it’s not too dull for you; if it’s any consolation, I hav...
Therefore, the coupling waveguide wall thickness has to be increasingly thin as the frequency increases, the design formula of the TE21-mode coupler is still applicable at the high-frequency region, if the waveguide wall thickness h < 0.05λ and the bandwidth is relatively narrow [17]....

The chemical composition of spodumene varies but is generally close to the ideal formula, LiAlSi2O6. The calculations yielded high molecular totals (average values of up to 103.0%; see Supplementary Table S1) but were still within acceptable error limits, considering the uncertainties in the determi...
