In recent years, analysis of college entrance examination papers across the country, electrochemical knowledge for the annual compulsory content. The main entrance exam examines the basic knowledge of electrochemical, the questions have multiple-choice questions, there are non-multiple-choice questions. The multiple-choice questions mainly examine the working principle of the primary battery and the electrolytic cell, such as the judgment of the electrode and the electrode product, the positive and the negative judgment of the electrode reaction type, the migration direction of the electrons or the ions, and the non-choice question mainly examines the writing of the electrode reaction type Chemical calculations, battery design, metal corrosion and protection. A test of the original battery, electrolysis cell comparison
