Vedclass · Answer

(A) Blood is a colloidal solution in which the dispersed phase particles are negatively charged. According to the Hardy-Schulze rule,the coagulating power of an electrolyte depends on the valency of the active ion (the ion carrying a charge opposite to that of the colloidal particles). Since blood particles are negatively charged,the positively charged $Fe^{3+}$ ions from $FeCl_3$ are effective in neutralizing the charge and causing coagulation,thereby stopping the bleeding.
