Answer 1

Hola!!!

HERE IS THE ANSWER

$heterogeneous \: solution \: in \: which \: the \: particle \: size \: is \: in \: between \: {10}^{ - 7} \: cm \: to \: {10}^{ - 5} \: cm, \: such \: that \: the \: solute \: particles \: neither dissolve \: not \: settle \: down \: in \: a \: solvent \: is \: called \: colloidal \: solution \: or \: \: colloid .$

The properties of colloids are↩

▶The particles of a colloidal solution are visible under a powerful microscope .

▶The particles of a colloidal solution do not settle down with the passage of time.

▶They can easily pass through filter paper.

▶Colloidal Solutions are not transparent or translucent in nature.

▶The Colloidal Solutions are heterogeneous in nature .

▶The particles of colloidal solution scatter light when a strong beam of light is passed through the colloidal solution, the path of beam becomes visible .

Hope it helps to you.
