对电解质溶液稀释的考查是高考的“热点”之一,多年来在全国各地高考化学试卷及理科综合试卷中几乎年年涉及这种题型.这种题型考查的知识点多,灵活性、综合性较强,有较好的区分度,它能有效地测试出学生对强弱电解质、电离平衡、电离度、水的电离、pH值、离子反应、盐类水解等基本概念的掌握程度及对这些知识的综合运用能力,故成为高考题中 Examination of the dilution of the electrolyte solution is one of the “hot spots ” of the college entrance examination, over the years in the national college entrance examination chemistry papers and science comprehensive papers covering almost every year of this type of questions. Sexual, comprehensive, better discrimination, it can effectively test out the students of the strong and weak electrolyte, ionization balance, ionization, water ionization, pH, ion reaction, salt hydrolysis and other basic concepts to master Degree and the comprehensive utilization of knowledge of these capabilities, it became the entrance exam questions
