The coagulating power of electrolytes with ions Na⁺,  Al³⁺, and Ba²⁺${ rise }^{}$for arsenic sulphide sol increases in the order :

1. $A{l}^{3+ }< B{a}^{2+ }< N{a}^{+}$

2. $N{a}^{+ }< B{a}^{2+ }< A{l}^{3+}$

3. $B{a}^{2+ }< N{a}^{+ }< A{l}^{3+}$

4. $A{l}^{3+ }< N{a}^{+ }< B{a}^{2+}$

The equation that represents a Freundlich adsorption isotherm is: 

1. $\frac{x}{m}=k{p}^{0.3}$

2. $\frac{x}{m}=k{p}^{2.5}$

3. $\frac{x}{m}=k{p}^{-0.5}$

4. $\frac{x}{m}=k{p}^{-1}$
