Coagulation value of the electrolyes AlCl3 and NaCl for As2s3 sol are 0.093 and 52 respectively. How many times AlCl3 has greater coagulating power than NaCl ?

Coagulation value of the electrolyes AlCl₃ and NaCl for As₂s₃ sol are 0.093 and 52 respectively. How many times AlCl₃ has greater coagulating power than NaCl ?

A
930
B
520
C
560
D
None of these

Solution:

$\frac{Coagulation power of {AlCl}_{3}}{Coagulation power of NaCl} = \frac{Coagulation value of NaCl}{Coagulation value of {AlCl}_{3}}$
$= \frac{52}{0 .093} = 559 .13 \approx 560$
