Arrhenius concept-. (Obj 18) a. - The products will be favored because the hydrogen sulfate ion is a stronger acid than the ammonium ion. HCl -> H + +Cl - (aq. acid base concept. 26 x 10-2 for HSO4- and is 5. The strong acid. a) H3PO4(aq) + H2O(l) H3O+(aq) + H2PO4(aq) b) NH4+(aq) + H2O(l) H3O+(aq) + NH3(aq) Base Ionization Constant • Base Ionization Constant (Kb): the equilibrium constant for the ionization reaction of a base with water • B + H2O OH- + BH+ • Large Kb = Strong base • Small Kb = Weak base Autoionization of Water Autoionization of Water. conjugate pairs acid base H 3 O + H 2 O. A conjugate acid is the product of a base. HPO4 2- (aq) + H2O (l) --> H2PO4-(aq) + OH-(aq) HPO42- and H2PO4- is a conjugate acid base pair. Of the pairs of substances on the list, only HSO₄⁻ and SO₄⁻² have similar structures, with the only difference being the number of protons. Conjugate acid of SO4 2- = HSO4- (hydrogen sulfite) SO4 2- does not have a conjugate base because you can't take away any H+. hydrophilic hydrophobic amphoteric isoprotic isoelectronic What is the concentration of H+ in a 2.
