Which of the following solutions is used in the styptic action which prevents bleeding of blood?
- A \(\mathrm{CoCl}_2\) solution
- B \(\mathrm{FeCl}_3\) solution
- C Gold sol
- D AgBr emulsion
Answer & Solution
Correct Answer
(B) \(\mathrm{FeCl}_3\) solution
Step-by-step Solution
Detailed explanation
Blood is a colloidal solution of an albuminoid substance. The styptic action of alum and ferric chloride solution is due to coagulation of blood forming a clot which stops further bleeding.
