Electro Chemistry

Explore core concepts of electro chemistry, including oxidation–reduction, electrodes, and energy conversion between chemical and electrical energy. Study galvanic cells, electrolysis, Faraday's laws, and corrosion prevention.

Explore the fundamentals of electrochemistry, including the relationship between chemical and electrical energy, oxidation and reduction, redox reactions, oxidation states, and balancing redox equations through half-reactions.

Explore how a galvanic cell converts chemical energy to electrical energy using a zinc–copper Daniell cell setup with two half-cells and a salt bridge.

Apply the Nernst equation to relate electrode potential to concentration changes, explaining standard electrode potentials at the cathode and anode and how cell potential varies with concentration.

Investigate how the conductance of electrolytic solutions depends on concentration, resistance, and electrode geometry, and learn to relate current, electrode distance, and cross-section area to conductance.

Explore Kohlrausch's law and its applications for calculating molar conductivity at infinite dilution, determining degree of dissociation and dissociation constant, and assessing solubility and conductivity in electrolytes.

Electrolysis drives a chemical change in an electrolyte by passing electricity through it, moving ions to electrodes where oxidation and reduction occur. Ions discharge at electrodes, depositing products.

Discover Faraday's laws of electrolysis, including the first and second laws, and how current controls electrode deposition and gold or silver plating in practical electrochemistry.

Explore the principles of batteries, including primary and secondary cells (rechargeable), lead-acid storage batteries, nickel-cadmium, and fuel cells, with attention to portability, internal resistance, and energy storage challenges.

Corrosion is an electrochemical decay of metals driven by moisture and oxygen, forming oxides or sulfates. Prevention uses barrier coatings, galvanization, electroplating, and sacrificial protection to block air and water.

Explore the electrochemical theory of rusting, detailing iron oxidation and reduction in water with oxygen and impurities to drive corrosion and energy.

Explore numerical problems in electrochemistry, calculating deposited masses and volumes, and electrode reactions using Faraday's laws, with copper, zinc, and magnesium electrolysis.

Apply numerical methods to determine the volume of gas liberated during electrolysis and the related electrode reactions. Learn how to compute gas yield and interpret redox processes in electrochemical systems.
