难溶电解质的溶度积为新课标中新增的内容,近几年高考题中频繁出现成为高考的热点.现从其高考命题的角度及规律方法予以探讨.一、考查角度探源角度1:利用溶度积常数计算判断离子沉淀的先后顺序典例(2013·新课标卷1·11)已知Ksp(AgCl)=1.56×10-10,Ksp(AgBr)=7.7×10-13,Ksp(Ag2CrO4)=9×10-11.某溶液中含有Cl-、Br-和CrO2-4,浓度均为0.010 mol/L,向该溶液中逐滴加入0.010 mol/L的AgNO3溶液时,三种阴离子产生沉淀的先后顺序为().
The solubility product of insoluble electrolyte is the new content in the new curriculum standard. In recent years, the college entrance examination questions frequently appear as the hot spot of college entrance examination.From the point of view of college entrance examination proposition and the rules and methods to be discussed. 1: Calculation of Precipitation by Solubility Product Constant Order Example (2013 · New Curriculum Vocabulary 1.11) Ksp (AgCl) = 1.56 × 10-10, Ksp (AgBr) = 7.7 × 10-13 , Ksp (Ag2CrO4) = 9 × 10-11. When some solutions contain Cl-, Br- and CrO2-4, the concentration is 0.010 mol / L, when 0.010 mol / L AgNO3 solution is added dropwise to the solution, Three kinds of anion precipitation occurred in the order ().
