Question

The coagulating power of an electrolyte for arsenious sulphide decreases in the order:

• A. $N{a}^{+}>A{l}^{3+}>B{a}^{2+}$
• B. $P{O}_4^{3-}>S{O}_4^{2-}>C{l}^{-}$
• C. $Cl>S{O}_4^{2-}>P{O}_4^{3-}$
• D. $A{l}^{3+}>B{a}^{2+}>N{a}^{+}$
• E. $N{a}^{+}>B{a}^{2+}>P{O}_4^{3-}$

Answer 1

Answer: (D)

Coagulating power of an electrolyte for arsenious sulphide decreases as $A{l}^{3+}>B{a}^{2+}>N{a}^{+}$
