Electrochemistry is a branch of chemistry, and it deals with the study of the production of electricity from the energy released during spontaneous chemical reactions and the use of electrical energy to bring about non-spontaneous requiring the input of external energy chemical transformation. Electrochemistry deals with how much chemical energy produced in a redox reaction can be converted into electrical energy. A redox reaction is that in which oxidation and reduction take place simultaneously. The arrangements used to bring about the chemical transformations are called electrochemical cells. The cells are used to convert chemical energy into electrical energy and electrical energy into chemical energy. There are two types of electrochemical cells :. Chemical cells are those in which electrical energy is produced only due to chemical changes occurring within the cell, and no transfer of matter takes place. Example: Batteries. Concentration cells in which electrical energy is produced due to physical changes involving the transfer of matter from one part of the cell to the other. For example — Standard hydrogen electrode.

Consider the following diagram in which an electrochemical cell is cou How long a current of 3 amperes has to be passed through a solution of Please Enter valid email. In primary batteries , the charging reaction occurs only once and after it has been used over a period of time , the battery becomes dead and cannot be refused mercury cell is more advantage than dry cell has a very short life span due to the conversion of zinc to zinc chloride that makes the zinc casing porous. Please choose valid name. The molar conductivity Lambda m of KCl solutions at different conce Switch Flag Bookmark. Due to this porous casing, the substance inside the cell leaks out and corrodes the metal, reducing the lifetime of the cell. Data given is not sufficient to predict. Text Solution.
