diffence between colidle and suspention
Answers
Answer:Colloidal solution :
★ A colloidal solution appears to be homogeneous but is actually heterogeneous.
★. The size of colloidal particles is between 10^-4 to 10-7 nunometres.
★ Colloidal particles are not visible with the naked eyes or a small microscope. The particles can be seen under an ultra microscope .
★ They pass through a filter paper.
★ They are also very stable , the colloidal particles do not settle on standing.
★ They scatter light and hence show tyndall effect .
Suspension :
★ It is a heterogeneous mixture .
★ The suspended particles are visible to the naked eyes.
★ The size of suspended particles is 10^-3 cm or more.
★ The suspended particles are retained over the filter paper .
★ Suspensions are unstable . The suspended particles settle down on standing .
★ Suspensions may show tyndall effect.
Explanation:
A colloid is a heterogeneous mixture in which the dispersed particles are intermediate in size between those of a solution and a suspension. The particles are spread evenly throughout the dispersion medium, which can be a solid, liquid, or gas.
