电化学是高考必考内容之一,每年的考题一般以选择题、填空题、简答题、实验题、计算题等形式出现,在题型上以传统题为主。但应用原理还是以电化学基础为出发点,学生在解答这类题时,只要有扎实的基础知识,并灵活运用,一般都能取得较好的成绩。电化学知识设计的考查点为:原电池、电解池、电镀池的构成及区别,电路中电子流向,电极反应类型与电极种类关系,金属活泼性与电极关系,阴阳极放电顺序及应用,电极反应式的书写,两级产物物质的量的关系,两级产物判断电解质溶液中离子浓度变化、pH变化,根据离子和电解产物与电子物质的量的关系的计 Electrochemistry is one of the contents of the college entrance examination. Each year’s exam questions usually appear in the form of multiple choice questions, blank questions, short answer questions, experimental questions, and calculation questions. The questions are usually based on traditional questions. However, the application principle is still based on the electrochemistry basis. When students answer such questions, as long as they have solid basic knowledge and flexible use, generally they can achieve better results. Electrochemical knowledge design examination points are: composition and difference of primary battery, electrolytic cell, electroplating cell, electron flow in the circuit, relationship between electrode reaction type and electrode type, metal activity and electrode relationship, cathode and anode discharge sequence and application, electrode Reaction writing, the relationship between the quantities of two-stage product substances, two-level products to determine changes in ion concentration in the electrolyte solution, pH changes, based on the relationship between ions and the amount of electrolytic products and electronic substances
