Question

Fe(OH)3 sol can be more easily coagulated by Na3PO4 in comparison to KCl because (A) mass of Na3PO4 is more than KCl hence it is more effective than KCl (B) phosphate ion (PO43-) has higher negative charge than Cl- ion hence are more effective for coagulation (C) KCl is more soluble than Na3PO4 hence less effective for coagulation (D) Na+ ions are more effective than K+ ions for coagulation.

Ferric hydroxide is a positively charged sol hence ions carrying negative charge can coagulate it. Since PO43- has higher negative charge than Cl- hence it is more effective for coagulation.

Q. $F e (O H)_{3}$ sol can be more easily coagulated by $N a_{3} P O_{4}$ in comparison to $K Cl$ because

mass of $N a_{3} P O_{4}$ is more than $K Cl$ hence it is more effective than $K Cl$

phosphate ion $(P O_{4}^{3 -})$ has higher negative charge than $C l^{-}$ ion hence are more effective for coagulation

$K Cl$ is more soluble than $N a_{3} P O_{4}$ hence less effective for coagulation

$N a^{+}$ ions are more effective than $K^{+}$ ions for coagulation.

Q. Fe(OH)3​ sol can be more easily coagulated by Na3​PO4​ in comparison to KCl because

mass of Na3​PO4​ is more than KCl hence it is more effective than KCl

phosphate ion (PO43−​) has higher negative charge than Cl− ion hence are more effective for coagulation

KCl is more soluble than Na3​PO4​ hence less effective for coagulation

Na+ ions are more effective than K+ ions for coagulation.
