WebJun 29, 2016 · The stronger the acid; the further to the right lies this equilibrium. Of course, the acidity is modified by the identity of the solvent. In water, the acid base reaction is often represented as: H X(g) + H 2O(l) ⇌ H 3O+ + X−. In water, for all the hydrogen halides, EXCEPT for H F, the equilibrium would lie almost quantitatively to the right. WebFeb 3, 2024 · A weak acid is one that only partially dissociates in water or an aqueous solution. The value of K a is used to calculate the pH of weak acids. The pK a value is used to choose a buffer when needed. Choosing an acid or base where pK a is close to the pH needed gives the best results. Relating pH, Ka, and pKa
