Colloidal solution appears to be homogeneous but actually it is heterogeneous. Give justification for this statement.
(N/A) The particles of a colloidal solution are very small,so they cannot be seen with the naked eye. Therefore,the colloidal solution appears to be homogeneous.
However,these particles are large enough to scatter a beam of visible light,i.e.,they exhibit the $Tyndall$ effect. Because they exhibit this property,which is characteristic of mixtures with distinct phases,the colloidal solution is actually heterogeneous.
