Discuss the relationship between wmax and the magnitude and sign of the free energy change for a reaction. Also discuss wmax for real processes. What is a reversible process?

Interpretation Introduction

Interpretation: Importance of electrolysis is given and the applications, the effect of electrolysis of aqueous NaCl and the purification of metal by electrolysis is to stated.

Concept introduction: Electrolysis is the process that takes place in an electrolytic cell and can be used for the refining of the metal and this technique has many industrial applications also.



The various applications of electrolysis are as follows,

  • It is used for the equivalent mass determination.
  • It is used for the electrolysis of water for the production of hydrogen gas.
  • Metals like Na,K,Al can be obtained by this process.
  • Electrometallurgy, electroplating can be obtain using electrolysis.

Electrolysis is a process that is carried out in an electrolytic cell and involves the gain or loss of the electrons and leads to a chemical change. This property leads to various applications of electrolysis.

The reduction potential of water is more than that of the sodium, which leads to the easy reduction of water over sodium and therefore the electrolysis of aqueous NaCl does not produce sodium metal under normal conditions
