Electrolytic Cells and Electrolysis
Electrolytic Cells and Electrolysis Electrolytic cells are devices that use electrical energy to drive a non-spontaneous chemical reaction. They consist of two electrodes (an anode and a cathode) immersed in an electrolyte solution. Here’s a basic overview: Components: Electrodes : Anode : The positive electrode where oxidation occurs. Cathode : The negative electrode where reduction occurs. Electrolyte : The ionic substance (liquid or molten) that allows ions to move between electrodes. Process: Electrolysis : The process of passing an electric current through the electrolyte, causing the chemical reaction. At the anode (positive electrode), oxidation occurs, meaning electrons are lost. At the cathode (negative electrode), reduction occurs, meaning electrons are gained. Examples: Electrolysis of Water : Overall reaction : 2H2O(l)→2H2(g)+O2(g)2H_2O(l) \rightarrow 2H_2(g) + O_2(g)2H2O(l)→2H2(g)+O2(g) At the cathode : 2H2O+2e−→H2+2OH−2H_2O + 2e^- \rightarrow H_2...
