What is the pH of a solution prepared by dissolving 0.458 g of aminobenzene into 200 mL of water? The following table provides p K a and K a values for selected weak acids. All values are from Martell, A. E.; Smith, R. M. Critical Stability Constants , Vols. 1–4. Plenum Press: New York, 1976. Unless otherwise stated, values are for 25 o C and zero ionic strength. Those values in brackets are considered less reliable. Weak acids are arranged alphabetically by the names of the neutral compounds from which they are derived. In some cases—such as acetic acid—the compound is the weak acid. In other cases—such as for the ammonium ion—the neutral compound is the conjugate base. Chemical formulas or structural formulas are shown for the fully protonated weak acid. Successive acid dissocation constants are provided for polyprotic weak acids; where there is ambiguity, the specific acidic proton is identified. To find the K b value for a conjugate weak base, recall that K a × K b = K w for a conjugate weak acid, HA, and its conjugate weak base, A–.
