Mock Test On Electrochemistry

Introduction: Dry cell is used to  power our electrical and electroic equipments because it generates electricity. Do you know how does a dry cell generate electricity? A chemical reaction occurs in it which generates electricity. Thus in a dry cell chemical electricity is converted into electrical energy. You are familiar with the electrolysis of solutions of ions. Eletrolysis is breaking down of ions compound by the passage of electricity. Breaking down of an electrolyte during electrolysis is a chemical reaction that takes place by the passage of electricity. Electrical energy is, thus, converted into chemical energy.Electrochemistry is the area of chemistry which is concerned with interconversion of chemical and electrical energy.It also deals with the resistance and conductance of aqueous electrolytic solutions. The determination of conductivities of aqueous electrolytic solutions provide an information on the extent of ionization of electrolytes in water.The current research in electrochemistry is focused on the design of fuel cells. The fuel cells are being explored as convenient and compact source of electricity.
