$A$ coagulating agent frequently added to water to remove the suspended and colloidal impurities is

Which ion has the maximum precipitation (flocculation) value for the precipitation of a positively charged colloidal solution?

$A$ precipitate is changed to a colloidal solution by the following process:

The coagulating power of electrolytes having ions $Na^{+}$,$Ba^{2+}$ and $Al^{3+}$ for arsenic sulphide sol increases in the order:

The disperse phase in colloidal iron $(III)$ hydroxide and colloidal gold is positively and negatively charged,respectively. Which of the following statements is $NOT$ correct?

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
