考点指要2015年高考理科综合第26题涉及电化学、物质分离提纯、溶解平衡等模块知识,主要考查考生对相关知识的掌握情况,从题干中获取信息、处理信息能力和探究能力。从统计数据上来看,该题考生失分严重。造成失分的主要原因主要有以下几个方面:1.基础知识有缺陷,基本概念和基本理论理解不透彻。电化学、平衡问题(化学平衡、电离平衡、水解平衡和难溶电解质的溶解平衡)和化学实验等一直是化学中的热点
Test points refers to the 2015 college entrance examination science comprehensive 26 questions related to electrochemical, material separation and purification, balance of dissolution and other modules of knowledge, mainly examine the candidates grasp the relevant knowledge, access to information from the stem, the ability to deal with information and inquiry skills. Statistics from the point of view, the problem serious loss of candidates. The main reasons for the loss of the main points are the following aspects: 1. The basic knowledge is flawed, the basic concepts and basic theory is not understood thoroughly. Electrochemistry, the balance of the problem (chemical equilibrium, ionization equilibrium, hydrolysis equilibrium and insoluble electrolyte equilibrium) and chemical experiments has always been a hot chemical
