Statement-1 : All colloidal dispersions give very low osmotic pressure...
The Tyndall effect is seen due to light scattering by particles in a colloid or particles in a fine suspension. So, solution particles show the Tyndall effect due to the scattering of light and scattering is directly proportional to the size of sol particles.
 
Also, colloidal particles have a high molar mass so, their mole fraction is very less causing low colligative properties and hence, all colloidal dispersion give very low osmotic pressure and show very small freezing point depression or boiling point elevation.
