《2015年江苏省高考说明》强调2015年化学科江苏卷的命题将按照“有利于科学选拔人才、促进学生健康发展、维护社会公平”的原则,进一步体现高中化学课程的“基础性、应用性、时代性”的特征,进一步体现化学科江苏卷的“宽基础、厚实践、重能力”的特色.电解质溶液中的物质浓度关系在选择题中属于难度较大的综合性题型,试题主要考查学生对电解质溶液中的电离平衡和水解平衡、物质的物料守恒和离子的电荷守恒的掌握和应用
The “2015 Jiangsu Provincial College Entrance Examination Explanation” emphasized that the propositions of the Jiangsu Chemicals Department in 2015 will be in accordance with the principle of “advantageous in selecting talents for science, promoting the healthy development of students, and maintaining social fairness,” and further embodying the “basic nature” of high school chemistry courses. The characteristics of “application, timeliness, and timeliness” further reflect the characteristics of “wide-basis, thick-practice, and heavy-capacity” of the Jiangsu Branch of the Chemistry Department. The relationship of the concentration of substances in the electrolyte solution is a difficult synthesis in multiple-choice questions. In the question type, the test questions mainly examine students’ understanding and application of the ionization balance and hydrolysis equilibrium in the electrolyte solution, the conservation of the material and the conservation of the charge of the ions in the electrolyte solution.
