Properties of Colloidal Solutions

For ${\mathrm{As}}_2{\mathrm{S}}_3$ sol, the most effective coagulating agent is

A cube of edge length $1 \mathrm{cm}$ is divided into smaller cubes of uniform size of length $1 \mathrm{nm}$. Assuming that no voids are present, the ratio of total surface area of all the cubes of $1 \mathrm{nm}$ edge length to the surface area of the initial cube is

Given below are two statements :
Statement $\mathrm{I}$ :
In the coagulation of a negative sol, the flocculating power of the three given ions is in the order -
${\mathrm{Al}}^{3+}>{\mathrm{Ba}}^{2+}>{\mathrm{Na}}^{+}$
