Definition of Raoult's law

Raoult's Law is the name of a thermodynamic postulate that alludes to the French chemist and physicist who instituted it around 1887: François Marie Raoult. This principle indicates that the vapor pressure (considered at a partial level) of each of the constituents of an ideal mixture based on liquids […]

Definition of chemical potential

The chemical potential is a thermodynamic quantity that describes the capacity of a substance to do chemical work, that is, its tendency to participate in a chemical reaction or to diffuse in a system. It is defined as the change in the free energy of a system when an infinitesimal amount of the substance is added, […]

Definition of collision theory

Collision theory is the name that identifies an old postulate, still valid and useful on a universal scale, which between 1916 and 1918 was promoted by a German chemist named Max Trautz and the British professor and chemist William Cudmore McCullagh Lewis. This content, closely linked to chemical kinetics, […]

Definition of desalination

Desalination is a word that accounts for the act and consequence of desalination, indicates the dictionary of the Royal Spanish Academy (RAE). Desalination, the theory goes, is the action carried out to remove salt from brackish water or seawater in order to make it drinkable or suitable […]

Definition of binding energy

Bond energy is the amount of energy needed to break down a chemical bond in a compound, separating its atoms into individual, gaseous states. This concept is fundamental in chemistry and nuclear physics, since it allows us to understand the stability of molecules and atomic nuclei. The binding energy is generally measured […]

Definition of absorption spectrum

The absorption spectrum is a graph that shows how a substance absorbs light or electromagnetic radiation at different wavelengths. It is generated when radiation energy is absorbed by the electrons of the atoms or molecules of a substance, causing transitions between different energy levels. This spectrum is unique to […]

Definition of composite materials

Composite materials is the name that experts in materials science give to elements made up of at least a couple of components that can be separated from each other with mechanical procedures and are easily distinguished individually. Composites, as they are usually described, are highly present resources in the world of […]

Definition of activation energy

Activation energy is a concept present in the field of chemical kinetics and other scientific specialties that refers to the minimum amount of energy required to start a process, phenomenon or activity. It is essential that the molecules of a system have a basic level of […]

Definition of fuel cells

Fuel cells are electrochemistry-based devices that generate electricity through a chemical reaction, usually between hydrogen and oxygen, without combustion. In a fuel cell, hydrogen is oxidized at the anode and oxygen is reduced at the cathode, producing water, heat and electricity as byproducts. This […]

Definition of chemical synthesis

Chemical synthesis is an essential procedure for the production of nanoparticles and certain drugs, for example. It is a resource or method that, thanks to the development of chemical compounds based on elemental or simpler substances, allows us to obtain chemical substances that do not exist in nature. To understand what chemical synthesis consists of, […]
