LEY DE LAS PROPORCIONES DEFINIDAS O LEY DE PROUST

La ley de las proporciones definidas, formulada por el químico francés Joseph Proust en 1794, establece que un compuesto siempre está formado por los mismos elementos en la misma proporción de masa, sin importar su origen o el método de preparación.

definidas establecida por el francés Joseph Proust en 1794

una consecuencia natural de la idea de que los elementos están formados por átomos idénticos e indestructibles. Proust realizó gran parte de su investigación en España y es allí donde logra determinar que la mezcla de elementos puede llevarse a cabo en una relación de peso continuo indistintamente del proceso inmediato que lo formó.

Example: I can't get the poetry of the trees,' he said. She nodded. Don't worry,' she said. You will someday. He believed her.' (Paterson, 4. 24)

Es por esto por lo que también se le conocía como ley de proporciones definidas. Para la industria y el ambiente de laboratorio, estas leyes son muy útiles en el cálculo de la cantidad de reactivos necesarios para la preparación de sustancias, así como el número de productos que debe ser producido.
