The 2010 college entrance examination syllabus (curriculum standards, experimental version): Chemistry on the water ionization and solution pH requirements are as follows: (1) understanding of water ionization, ion product constant. (2) understand the definition of solution pH. To understand the method of determining solution pH, simple calculation of pH can be carried out. Personal opinion: personal opinion: The topic of acid-base ionization and solution of water in the college entrance examination mainly studied from the following points: 1) know ion product constant depends only on the temperature of 2) to calculate the number of solution pH and weak electrolyte water of ionized hydrogen and hydroxyl radicals. 3) to correctly determine the factors affecting the ionization balance of water and to explain some phenomena. Two. Thematic analysis The main points of this chapter are summarized as follows: Comparison of pH in the same concentration solution (09, two, -10, 09, Chongqing, -10,, Chongqing, -9) PH Mixed solution pH (09 Beijing, -11, 07, one -7, 06 Guangdong, -14,, Tianjin, -11) Water ionized C (H+) problem (08, Shanghai, -11) Concept theorem Ion product (06, one -7), conductivity (08 Guangdong, -18) three major conservation (09 national one -6) Factors affecting the ionization balance of water 09 Tianjin, -4, 09, Shanghai, -20, 08, Beijing, -6, and Chongqing, -11, A question: pH questions: [1] (Chongqing 09 -10) the solution concentration of 10. of the same material, pH arranged from big to small right is A.Ba (OH) 2, Na2SO3, FeCl3, KCl, B.Na2SiO3, Na2CO3, KNO3, NH4Cl, C.NH3, H2O, H3PO4, Na2SO4, H2SO4,
