WebNov 4, 2024 · The pH of the solution formed by the reaction of a weak acid with a weak base depends on the relative strengths of the reactants. For example, if the acid HClO has a K a of 3.4 x 10 -8 and the base NH 3 has a K b = 1.6 x 10 -5 , then the aqueous solution of HClO and NH 3 will be basic because the K a of HClO is less than the K a of NH 3 . WebComparing the values of K a for the acidic cation and K b for the basic anion, we determine the solution will be acidic because K a > K b. When K a ≈ K b, a Neutral Solution is Formed. One more possibility is when the salt of a weak acid and weak base produces a neutral solution. This is somewhat similar to what we saw for salts containing ... ctv morning show ottawa

WebAug 14, 2024 · Consequently, the two effects cancel, and the solution remains neutral. With salts in which the cation is a stronger acid than the anion is a base, the final solution has a pH < 7.00. Conversely, if the cation is a weaker acid than the anion is a base, the final solution has a pH > 7.00. WebThe pH of a salt solution is determined by its component anions and cations. Salts that contain pH-neutral anions and the hydronium ion-producing cations form a solution with a pH less than 7. For example, in ammonium nitrate (NH 4 NO 3) solution, NO 3− ions do not react with water whereas NH 4+ ions produce the hydronium ions resulting in ... WebA generic equation for this process is shown below: HA + BOH BA + H2O The salt's negative ion (A -) is the conjugate base of the acid HA while the salt's positive ion (B +) is the conjugate acid of the base BOH. Depending on the strength of the acid and base, the resulting solution may be acidic, basic, or neutral. ctv morning show regina
