The most effective coagulating agent among the options for $\mathrm{Sb}_{2} \mathrm{~S}_{3}$ solution is $\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}$ because $\mathrm{Sb}_{2} \mathrm{~S}_{3}$ is a negative solution. $\mathrm{Al}_{2}\left(\mathrm{SO}_{4}\right)_{3}$ will be the most effective coagulant due to higher charge density on $\mathrm{Al}^{3+}$ by the Hardy-Schulze rule.

For the coagulation of a negative solution, the species below, that has the highest flocculation power is:
1 $\mathrm{Ba}^{2+}$
2 $\mathrm{Na}^{+}$
3 $\mathrm{PO}_{4}^{3-}$
4 $\mathrm{SO}_{4}^{2-}$
Explanation:
The coagulation of negative solution, the higher charge containing ions have the highest flocculating power. So, $\mathrm{Ba}^{2+}$ has highest flocculating power.

Zeta potential is
1 Potential required to bring about coagulation of a colloidal solution.
2 Potential required to give the particle a speed of $1 \mathrm{~cm} \mathrm{~s}^{-1}$
3 Potential difference between fixed charged layer and the diffused layer having opposite charges
4 Potential energy of the colloidal particles.
Explanation:
The charges of opposite signs on the fixed and diffused part of the double layer results in a difference in potential between these layers in the same manner as potential difference is developed in a capacitor. This potential difference between the fixed layer and the diffused layer of opposite charges is called the zeta potential.

Bleeding due to a cut can be stopped by applying ferric chloride solution in the laboratory. This is due to
1 coagulation of negatively charged blood particles by $\mathrm{Fe}^{3+}$ ions.
2 coagulation of positively charged blood particles by $\mathrm{Cl}^{-}$ions.
3 reaction taking place between ferric ions and the hemoglobin forming a complex.
4 common element, iron, in both $\mathrm{FeCl}_{3}$ and hemoglobin.
