On which of the following properties does coagulating power of an ion depend?

The coagulation of $200 \ mL$ of a positive colloid took place when $0.73 \ g$ of $HCl$ was added to it. The flocculation value of $HCl$ for the colloid is

Molar conductivity $\left(\Lambda_m\right)$ of an aqueous solution of sodium stearate,which behaves as a strong electrolyte,is recorded at varying concentrations $(c)$ of sodium stearate. Which one of the following plots provides the correct representation of micelle formation in the solution? (Critical micelle concentration $(CMC)$ is marked with an arrow in the figures.)

Under the influence of an electric field,the particles in a sol migrate towards the cathode. The coagulation of the same sol is studied using $NaCl$,$Na_2SO_4$,and $Na_3PO_4$ solutions. Their coagulating values will be in the order:

$100 \ mL$ of $0.0018\%(w/v)$ solution of $Cl^{-}$ ion was the minimum concentration of $Cl^{-}$ required to precipitate a negative sol in one $h$. The coagulating value of $Cl^{-}$ ion is $.......$ (Nearest integer).
