“11th Class Chemistry Chapter 10 Quiz: Electrochemistry” reveals the connection between chemical reactions and electrical energy—a very vital concept to understand most of the applications in chemistry and in our day-to-day life. This chapter is particularly important for MDCAT students as it covers basic principles that are directly relevant to practical chemistry and exam questions. Our MDCAT Quiz for this chapter will help you assess your understanding and prepare you for MDCAT-related questions.
The chapter introduces the electrochemical cells, which are devices that convert chemical energy into electrical energy. Students learn about galvanic cells, where spontaneous redox reactions produce electrical energy. It explains the electrodes in these cells, where the anode is the site of oxidation and the cathode the site of reduction. The concept of oxidation-reduction reactions (redox) is discussed in detail, where students learn how electrons are transferred from one reactant to another during these reactions.
The chapter goes on to describe electrolysis, wherein electrical energy is used to drive a non-spontaneous chemical reaction. The student learns about the electrolytic cell, where an external power source causes the decomposition of compounds—that is, electrolysis of water to give hydrogen and oxygen. The application of electrolysis in electroplating and the extraction of metals is also discussed, as well as how the Faraday laws of electrolysis describe the relationship between the amount of substance deposited or liberated during electrolysis and the amount of electric charge passed through the electrolyte.
