WebFeb 3, 2024 · K a is the equilibrium constant for the dissociation reaction of a weak acid. 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 ... WebThe pH is then calculated using the expression: pH = - log [H 3 O +]. Example: Find the pH of a 0.0025 M HCl solution. The HCl is a strong acid and is 100% ionized in water. The hydronium ion concentration is 0.0025 M. Thus: pH = - log (0.0025) = - ( - 2.60) = 2.60 Top Calculating the Hydronium Ion Concentration from pH
