Electrolysis quantitative aspects

The Quantitative Aspects of Electrolysis activity in eChapter 18.13 walks you through the steps for calculating the mass of metal that can be produced by an electrolytic cell for a given time at a certain current. Write down each of the steps required for the problem given then use a similar procedure to determine the mass of copper that can be produced by passing a current of 18.0 A through a solution of copper(II) ions for 1.0 hour. 

In electrolysis cells, chemical reactions are produced by electric currents. (Section 17.4) Quantitative aspects of electrolysis reactions are presented in Section 17.5. 

This chapter explains the fundamental principles and applications of electrochemical cells, the thermodynamics OF electrochemical reactions, and the cause and prevention of corrosion BY ELECTROCHEMICAL MEANS. SOME SIMPLE ELECTROLYTIC processes and the QUANTITATIVE ASPECTS OF ELECTROLYSIS ARE ALSO discussed. 

In contrast to spontaneous redox reactions, which result in the conversion of chemical energy into electrical energy, electrolysis is the process in which electrical energy is used to cause a nonspontaneous chemical reaction to occur. An electrolytic cell is an apparatus for carrying out electrolysis. The same principles underlie electrolysis and the processes that take place in electrochemical cells. Here we will discuss three examples of electrolysis based on those principles. Then we will look at the quantitative aspects of electrolysis. 

Finally, we explore a nonspontaneous electrochemical process—electrolysis— and leam the quantitative aspects of electrolytic processes. (19.8)... 

The basic electroanalytical experiment always consists of applying a potential to the electrode and recording the current. The quantitative aspects will be considered in some detail in later sections. However, it is first very important to have a phenomenological understanding of what happens at the electrode-solution interface, how concentrations change once the electrolysis starts, and how those changes control the current flow (often called the electrochemical signal or response).

The electrochemistry section (Chapter 20) has been expanded to include basic electrochemical terms and quantitative aspects of electrolysis. 

One of the attractive features of SECM is that the UME tip response is based on well-established electrochemical principles, making the technique quantitative. This aspect of SECM can be illustrated by considering the case of simple diffusion-limited electrolysis at an amperometric disk-shaped tip. When the tip is positioned a long way from the target...
