raoults

Raoults is not a standard term in science or scholarship; it is the plural form of the surname Raoult and does not designate a single subject by itself. In English-language texts, discussions about ideas named after François-Marie Raoult typically use the possessive form "Raoult's" rather than "Raoults."

Raoult's law is the best-known concept associated with the name, and it is a fundamental principle in physical chemistry. It states that for an ideal solution, the partial vapor pressure of each volatile component equals the product of its mole fraction in the solution and its vapor pressure as a pure substance. The total vapor pressure of the solution is the sum of these partial pressures. The law helps explain why solutions vaporize and boil at lower temperatures than the pure solvents. It is most accurate for ideal or near-ideal solutions; deviations occur in non-ideal mixtures due to molecular interactions, which are accounted for by activity coefficients in more advanced models.

Notable individuals with the surname Raoult include François-Marie Raoult (1830–1901), a French chemist who formulated what is known as Raoult's law, and Didier Raoult (born 1952), a French microbiologist and founder of the IHU Méditerranée Infection in Marseille, recognized for his extensive work on infectious diseases and his public-facing views during contemporary health debates.

In bibliographic or genealogical contexts, "Raoults" may appear when referring collectively to people bearing the surname Raoult. In scientific writing, the standard practice is to use "Raoult" for the person or "Raoult's" for concepts named after the individual.
