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. ICE tables are usually used for weak acid or weak base reactions because all of the nature of these solutions. 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. Acid Dissociation constant: When a weak acid reacts with a base the product is in equilibrium with the reactant because it produces a strong conjugate base. A conjugate acid-base pair is a pair of acid and base that only differs with the presence or absence of a proton of H+. Cl- ...
