考点定位:高考对电化学的考查主要集中在几个方面:原电池和电解池的工作原理、电化学的应用、电解规律及相关计算,特别是电极反应式的书写等。高考题往往以陌生的情境材料为信息进行考查。原电池、电解池的工作原理主要以选择题的形式出现,电极反应式的书写主要以填空题的形式出现。可以预测2014年高考仍将以传统题型为主,其中,原电池和电解池的工作原理、应用仍是高考命题的重点;特别是电极反应式的书写考点必将出现。考点一、原电池的工作原理例1(2013·江苏卷)Mg-H2O2电池可用
Test location: college entrance examination of the electrochemical focus on several aspects: the original battery and electrolytic cell working principle, the application of electrochemical, electrolytic law and related calculations, especially the electrode reaction type of writing. College entrance exam questions often unfamiliar situation information for the test. The working principle of primary batteries and electrolytic cells mainly appears in the form of multiple choice questions. The writing of electrode reaction type mainly appears in the form of blank filling questions. Can predict the 2014 college entrance examination will still be based on the traditional type, of which the original battery and electrolytic cell working principle, the application is still the focus of college entrance examination proposition; especially the electrode reaction writing test center will appear. A test site, the working principle of the original battery Example 1 (2013 Jiangsu volume) Mg-H2O2 battery is available
