Which of the following colloids are formed when hydrogen sulphide gas is passed through a cold solution of arsenious oxide?

The migration of positively charged colloidal particles under an electrical field towards the cathode is called:

Gold sol is an electronegative sol. The amount of electrolyte required to coagulate a certain amount of gold sol is minimum in the case of

Give information about the applications of colloids.

The surface tension of a hydrophilic sol is:

The correct statements about the properties of colloidal solutions are:
$A$. Tyndall effect is used to distinguish between a colloidal solution and a true solution
$B$. Zeta potential is related to movement of colloidal particles
$C$. Brownian motion in colloidal solution is faster if the viscosity of the solution is very high.
$D$. Brownian motion stabilises the sols
