Acids with a K a … Web19 de dez. de 2024 · The reason is that strong acids have p K a values that are poorly known. These p K a s cannot be determined directly, because the exact concentration of the ions is difficult to know with precision: the electrodes do not react with the concentration of H X + or H X 3 O X + ions.

WebThe higher the Ka, the stronger the acid is, and the weaker its conjugate base is. Similarly, the higher the K b, the stronger the substance is as a base, and the more weakly acidic its conjugate acid is. Read also : What happens to water molecules when equilibrium is reached? What do KA and KB values say about acid and base strength? WebpKa Values of Common Bases Values in H 2O as much as possible, so common comparisons (i.e., H 2OpK a = 15.7) can still be used Note; The pK a values associated with bases is normally meant to refer to the true pK a's of their conjugate acids; i.e., pK a associated with HO-is 15.7, which is the pK a of H 2O. This is often sloppily used by WebIntroductory acid base worksheet (and complete solution answer key) starting with basic logarithms and pH (extending to pOH, pKa, pKb and pKw). Students are required to calculate pH and pOH from given concentrations of strong acids and bases as well as calculate pH, pOH, [H3O+], [OH-], given one and determine the other three. dark archives pf2e
