Vedclass · Answer

(A) Blood is a colloidal system in which the dispersed phase consists of negatively charged particles (like albumin and other proteins). According to the Hardy-Schulze law,the coagulating power of an ion increases with the increase in the magnitude of the charge on the ion. $FeCl_3$ dissociates to provide $Fe^{3+}$ ions. Since $Fe^{3+}$ ions are highly positively charged,they effectively neutralize the negative charge on the blood colloids,leading to coagulation and stopping the bleeding.
