Physical Chemistry
- Physical chemistry is the branch of chemistry that explores the physical principles underlying chemical reactions and processes.
- It focuses on the physical properties and behavior of molecules and reactions, encompassing four main subfields:
- Thermodynamics, which studies energy relationships and transformations in chemical systems.
- Kinetics, which examines the rates of chemical reactions.
- Quantum Mechanics, which delves into the behavior of matter at the atomic and subatomic level.
- Spectroscopy, which investigates the interaction between matter and electromagnetic radiation.
Electrochemistry
- Electrochemistry is the branch of chemistry that examines the relationship between chemical reactions and electricity.
- It involves the transfer of electrons between atoms or molecules, and is characterized by key concepts such as:
- Oxidation, which is the loss of electrons by an atom or molecule.
- Reduction, which is the gain of electrons by an atom or molecule.
- Electrochemical cells, which are devices that convert chemical energy into electrical energy or vice versa.
- Electrolysis, which is the process of driving a chemical reaction using an electric current.
- Electrodes, which are the surfaces where oxidation or reduction occurs.
- Half-cells, which are parts of an electrochemical cell where either oxidation or reduction occurs.
- Cell potential, which is the potential difference between two half-cells in an electrochemical cell.
Key Electrochemical Processes
- Corrosion is the oxidation of a metal in the presence of oxygen and moisture.
- Batteries are devices that store electrical energy in the form of chemical energy.
- Fuel cells are devices that convert chemical energy into electrical energy.
- Electroplating is the process of depositing a thin layer of a metal onto another metal using an electric current.
