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
