List of weak acids and conjugate bases

WebIn chemistry, the definition of a buffer is a solution that can resist pH change upon the addition of an acid or a base. It consists of a solution of a weak acid and its conjugate base, or vice versa. A buffer is an extremely useful solution used in acid base chemistry. Sometimes, when solutions mix with a strong acid or base, the pH can change ... Webfully 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 Kb value for a conjugate weak base, recall that Ka × Kb = Kw for a conjugate weak acid, HA, and its conjugate weak base, A–. Compound Conjugate Acid pKa Ka
