    Table of Common Ka Values for Weak Acids - ThoughtCo

    K a is the equilibrium constant for the dissociation reaction of a weak acid.A weak acid is one which only partially dissociates in water or an aqueous solution. The value of K a is used to calculate 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.
