Highest pka
WebThe acid with the highest pKa among HClO, HIO, and HBrO is HIO. b. For a weak acid H3Y, the acid dissociation constant can be represented by Ka= [HY2−] [H3O+] / [H2Y−] [H2O] c. Binary acids with higher values of Ka have weaker bonds between the atoms. d. If acid HA has a lower pKa than acid HX, then HX has a weaker conjugate base than HA. WebAs, the pk a value is inversely proportional K a, hence the value of pk a decreases with the increase in the value of the acidic strength. Step 3: Hydrogen halides of the highest pK …

Web7 de fev. de 2015 · The highest pKa value means the weakest acid. Why not look up the Ka or pKa values and see. HClO3 and HClO4 are both strong acids, and therefore will not have the highest pKa. Between Cl, Br, and I the LEAST electronegative is I, meaning it wont pull the electrons towards itself as much as Cl or Br, so it wont weaken the H bond as much.
