Question

Compare the coagulation power of HCl with KBr. Given the coagulation values are 30.8 and 138 respectively. 

Moderate
Solution

The coagulation power is inversely proportional to coagulation value, the ratio of their coagulation power is 

 Coagulation power of HCl Coagulation power of KBr= Coagulation value of KBr Coagulation value of HCl=13830.8=4.48

HCl has 4.48 times greater coagulation power than KBr.
