Answer 2

Answer:

D) K2SO4.Al2(SO4)3

Explanation:

K2SO4.Al2(SO4)3 is simply Potash alum.

According to IUPAC it is called as Aluminium potassium sulfate dodecahydrate. Potash alum is commonly referred to as fitkari, it is known for its coagulating property with the blood.

The Al+3 ions act and neutralizes the charges on blood and forms an immediate clot. the blood contains negatively charged colloidal particles which are neutralizes by the positively charged Aluminium ions (Al+3).
