Coagulation value of the electrolytes `AlCl_(3)` and NaCl for `As_(2)S_(3)` sol are 0.093 and 52 respectively. How many times `AlCl_(3)` has greater coagulating power than NaCl?

A

930

B

520

C

560

D

None of these

Text Solution

Verified by Experts

The correct Answer is:
C
`("Coagulation power of AICI_(3)")/("Coagulation power of NaCl")`
`=("Coagulation value of NaCl")/ ("Coagulation value of AlCl_(3)")`
`=(52)/(0.093)=559.13~~560`

The coagulation power of an electrolyte for As_(2) S_(3) decreases in the order:

Al(NO_3) has higher coagulating power then MgSO_4 for Fe(OH)_3 sol.

The coagulation values in millimoles per litre of the electrolytes used for the coagulation of As_(2)S_(3) are given : I (NaCl) = 52, their coagulating power is
