Is f a weak base
WebSep 3, 2024 · Answer: pH = 4.3 Explanation: The pH of a buffer solution and its conjugate base can be determine by the Henderson-Hasselbach Equation.It can be estimated because equilibrium between weak acid and its conjugate base allows the solution to not change pH when small amounts of strong acid or base are added. WebA weak base is any base that reacts with water (accepts H + ions) to a very small extent, usually less than 5 - 10%. An aqueous solution of a weak base in a state of equilibrium would consist mainly of the unionized form of the base, and only a small amount of hydroxide ions and of the cation (conjugate acid) of the weak base.
