Ion balance in aqueous solution is the extension and application of chemical equilibrium, but also one of the contents of the test center in the college entrance examination distribution more. Which sediment dissolution balance is the new knowledge points in the new curriculum standard, the questions are mainly the multiple choice and fill in the blank, The main contents of the test are: (1) ionization balance. (2) Judgment of acidity and alkalinity of acid and alkali mixed solution and simple calculation of pH. (3) Influence of salt on water ionization equilibrium and salt solution evaporated ) After the judgment of the product (4) electrolyte solution ion concentration in the size of comparison.
