Speciation in Weak Electrolytes

The solution speciation here means a list of the ions and molecules as well as their concentrations. A weak electrolyte, for example, HA (weak acid) or BOH (weak base), when dissolved in a solvent (water), consists of both neutral molecules and ions due to the following reactions  [Pg.19]

The total concentration of the weak electrolyte (e.g., with a weak acid) is a sum of the concentration of ions and molecules, ha = HA(aq) + H+(aq) = HA(aq) + a (aq) (mass balance equation), and the solution should be electrically neutral, that is, H+(aq) = A-(aq) (chaTge balauce equation), in addition to the relationship between all concentrations in accordance with the law of mass action  [Pg.20]

Friedrich Wilhelm Ostwald (1853-1932) was a Baltic German physical chemist, who was awarded the Nobel Prize in Chemistry in 1909 for his work on a nnmber of chemical problems inclnding chemical equilibria and kinetics. He was one of the first scientists to develop a theory of electrolyte solutions. [Pg.21]
