Las mezclas homogéneas son aquellas en las que los componentes de la mezcla no son identificables a simple vista. Una mezcla homogénea importante de nuestro planeta es el aire. El aire estáformado por varios componentes como:
Oxígeno: Elemento O.
Nitrógeno: Elemento N.
Dióxido de carbono: Compuesto CO2
Vapor de agua
Otros gases en menor cantidad.
Entre las mezclas homogéneas sedistingue un tipo especial denominado disolución o solución. Al componente que se encuentra en mayor cantidad se le denomina solvente o disolvente y al que se encuentra en menor cantidad, soluto.CARACTERISTICAS
CARACTERISTICA DE LAS MEZCLAS
1.) Está formada por la unión de dos o más sustancias (componentes).
2.) los componentes se encuentran en proporciones variables.
3.) Cadacomponente conserva sus propiedades.
4.) los componentes se pueden separar por procedimientos mecánicos y/o físicos.

 
Las características de las mezclas homogéneas son:
•
su aspecto uniforme(homogéneo)en todas sus partes,
•
sus componentes no se distinguen a simple vista
•
no sedimentan
•
atraviesan todos los filtros
•
sus componentes se pueden separar por métodos químicos ofisico-químicos los otros tipos de separación también por la absorción atómicade 2 cuerpos o más
