(D) Potash alum $(K_2SO_4 \cdot Al_2(SO_4)_3 \cdot 24H_2O)$ is a salt that provides $Al^{3+}$ ions. Blood is a colloidal solution of negatively charged particles. When potash alum is applied to a cut,the $Al^{3+}$ ions neutralize the charge on the blood colloids,causing them to coagulate. Thus,alum acts as a coagulating agent to stop the bleeding.
