Suspension - class-IX
Suspension is a heterogeneous mixture in which very fine particles of a solid are dispersed in any medium (liquid or gas). Fine particles of the solid remain suspended in the medium.
A suspension is a heterogeneous mixture in which very fine particles of a solid are dispersed in any medium (liquid or gas). Fine particles of the solid remain suspended in the medium.
Following are the characteristics properties of suspensions
i) Heterogeneous nature: a suspension is a heterogeneous system.
ii) Visibility: the particles in a suspension can be seen with naked eyes or under a simple microscope.
iii) Particle Size: in a suspension, the size of the particles is of the order of 10-7 make or larger.
iv) Sedimentation: the particles in a suspension travel tendency to settle down. Very fine particles, however, remain suspended in the medium.
v) Separation by filtration: Larger particles in a suspension can be separated from the liquid or air by the filtration.
