Which of the following solutions is used in the styptic action which prevents bleeding of blood?
Show Hint
- CoCl2 solution
- FeCl3 solution
- Gold sol
- AgBr emulsion
The Correct Option is B
Solution and Explanation
The solution that is used in the styptic action to prevent bleeding is FeCl\(_3\) (Iron (III) chloride) solution. It has astringent properties and is used to stop bleeding by constricting blood vessels and promoting blood clotting. It is commonly used in cases of minor cuts or wounds.
