Question

Colloidal solution of solid in liquid is called ________.

Answer 1

A colloidal solution is classified on the basis of dispersion phase and dispersion medium.
Here, the dispersion phase is $Solid$ and the dispersion medium is $liquid$, so the colloidal solution is called $Sol$.
Note: $Sol$ should not be confused with $SolidSol$ which has dispersion phase as $Solid$ and the dispersion medium is also $Solid$.
