Descriptor presión osmótica
Entry term(s) choque osmótico
Scope note: Presión requerida para impedir el paso de solvente a través de una membrana semipermeable que separa un solvente puro de una solución de solvente y soluto o que separa diferentes concentraciones de una solución. Es proporcional a la osmolaridad de la solución.
