The ionisation constant of nh4+ in water

Web(d) The NH4+NH4+ ion is acidic (see above discussion) and the F− ion is basic (conjugate base of the weak acid HF). Comparing the two ionization constants: Ka of NH4+NH4+ is 5.6 × 10−10 and the Kb of F− is 1.6 × 10−11, so the solution is … Webin all aqueous solutions, the concentration of water is essentially the same, about 1000/18.0 or 55 mol/liter. Therefore, [H 2O] can be combined with K c to give a new constant K w, the dissociation constant of water. K w = [H +] [OH-] = 1.0 x 10-14 at 25°C Since water dissociates into equal amounts of these two ions, we can calculate
