Most suitable salt which can be used for efficient clotting of blood will be?

Options

A ${FeCl}_{3}$
BMg{ $\left({HCO}_{3}\right)}_{2}$
C ${FeSO}_{4}$
D ${NaHCO}_{3}$

Correct answer

A. ${FeCl}_{3}$

Step-by-step solution

Blood is a negatively charged sol.

Blood being a colloidal solution, its coagulation by Hardy-Shuze's law states " Higher the charge on cation higher will be its efficiency to coagulate the colloidal solution"

According to Hardy-Schulz's rule, the cation with high charge has high coagulation power.

${FeCl}_{3}$ has ${Fe}^{+ 3}$ ions.
