Overview
Electrochemistry is the branch of chemistry that studies the conversion of chemical energy into electrical energy and electrical energy into chemical energy, along with their mutual relationship. The chapter connects redox reactions, galvanic cells, electrolytic cells, electrode potential, electroch
Key Concepts
Electrochemistry deals with the study
Electrochemistry deals with the study of conversion of chemical energy into electrical energy or vice versa and their mutual relationship. Redox react
A galvanic cell converts chemical energy
A galvanic cell converts chemical energy into electrical energy through a spontaneous redox reaction. Examples include Daniell cell, Volta cell, Lecla
An electrolytic cell converts electrical energy
An electrolytic cell converts electrical energy into chemical energy by passing direct current through an electrolyte or fused salt, causing a non-spo
Oxidation takes place at the anode
Oxidation takes place at the anode and reduction takes place at the cathode. In a galvanic cell, the anode is negative and the cathode is positive. El
A salt bridge is a U
A salt bridge is a U-shaped tube filled with an inert electrolyte in a gelatin or agar-agar paste. It completes the circuit and maintains electrical n
Learning Objectives
