When dissolved in water, iron(III) chloride undergoes hydrolysis and gives off heat in an exothermic reaction. The resulting brown, acidic, and corrosive solution is used as a coagulant.

The answer given in the sample paper is :
FeCl3 helps in better and faster clotting of wounds.
enough for a 1 marker.
i think it forms a complex with blood plasma's ions.
