Gyöngyi Nagyné Kiss M.D.,Ph.D. Department of biochemistry and medical chemistry University of Pecs, Medical school The law of mass action The law of mass action: Write the law of mass action for each of the following reactions: Equilibria in solutions of weak acids Reaction equation of the electrolytic dissociation of a weak acid in an aqueos solution: The acid dissociation constant: Equilibria in solutions of weak acids Example 1.: Reaction equation of the electrolytic dissociation of a HF in an aqueos solution: The law of mass action: The acid dissociation constant: Equilibria in solutions of weak acids Example 2.: Reaction equation of the electrolytic dissociation of a benzoic acid in an aqueos solution: The law of mass action: The acid dissociation constant: Equilibria in solutions of weak bases Reaction equation of the electrolytic dissociation of a weak base in an aqueos solution: The base dissociation constant: Equilibria in solutions of weak bases Example 1.: Reaction equation of the electrolytic dissociation of NH3 in an aqueos solution: The law of mass action: The base dissociation constant: Equilibria in solutions of weak bases Example 2.: Reaction equation of the electrolytic dissociation of aniline in an aqueos solution: The law of mass action: The base dissociation constant: Products predominate over reactants. Reactants predominate over products. The reaction proceeds nearly to completion. The reaction hardly proceeds at all. Appreciable concentrations of both reactants and products are present. ? Pressure changes on solids and liquids can be ignored because the volume (and concentration) of a solid or a liquid is nearly independent of pressure. ? ? ? ? ? ? ? ? Ksp constant is called the solubility product constant, or simply the solubility product.
