Question: Define the following electrochemistry terms and provide an example for each: (i) Electrolysis, (ii) Electrolytic cell, (iii) Electrochemical cell, (iv) Ions and electrodes, and (v) 1 faraday. Answer: (i) Electrolysis is a process in which an electric current is passed through an electrolyte to induce a non-spontaneous redox reaction, such as the decomposition of water into hydrogen and oxygen gases. (ii) An electrolytic cell is an apparatus using an external electrical source to drive a non-spontaneous electrochemical reaction, like the electrolysis of molten sodium chloride to produce sodium metal and chlorine gas. (iii) An electrochemical cell converts chemical energy into electrical energy through spontaneous redox reactions, for example, the Daniell cell. (iv) Ions are charged particles, while electrodes are conductive materials facilitating electron transfer in an electrochemical process, as seen in the electrolysis of copper sulfate. (v) 1 faraday is a unit of electrical charge equal to the charge carried by one mole of electrons, approximately 96,485 coulombs, used in electrochemistry calculations like determining the amount of substance produced during electrolysis.
