Web25 apr. 2024 · KF creates the F- ion in solution. Since HF is a weak acid, its conjugate base, F-, must be a strong base. Strong. A weak base is BASE-ically a solution that partially dissociates in water, which means that in a ionic compound only some of the compound breaks up into ions. So, in this case, the entire KF compound breaks up into ions WebFirst, write the equation for the ionization of the weak acid, in this case of hydrogen carbonate. Although this step is not truly necessary to solve the problem, it is helpful in identifying the weak acid and its conjugate base. HCO3-(aq) + H2O(l) --> H3O+(aq) + CO32-(aq) Second, added strong acid will react with the conjugate base, CO32-.
