sol can be more easily coagulated by 
in comparison than KCl because
A
Mass of 
is more than KCl hence it is more effective than KCl
is more than KCl hence it is more effective than KCl
B
Phosphate ion 
has higher negative charge than 
ion hence are more effective for coagulations
has higher negative charge than ion hence are more effective for coagulations
C
KCl is more soluble than 
hence less effective for coagulations
hence less effective for coagulations
D
ions are more effective than 
ions for coagulations
Text Solution
Verified by ExpertsThe correct answer is:
B
Ferric hydroxide is a positively charged sol hence ions carrying negative charge can coagulate it. Since 
has higher negative charge than 
hence it is more effective for coagulations.
