The magnitude of colligative properties in all colloidal dispersions is $....$ than true solutions.

Identify the dispersed phase and dispersion medium in fog,respectively.

Identify the method of preparation of a colloidal sol from the following.

Lyophobic colloids are:

The charge of $SnO_2$-sol in alkaline and acidic medium are respectively (Hint: $SnO_2$ is amphoteric oxide).

$Statement-1$: Micelles are formed by surfactant molecules above the critical micellar concentration $(CMC)$.
$Statement-2$: The conductivity of a solution having surfactant molecules decreases sharply at the $CMC$.
