During bleeding from cut $FeCl_3$ is used to stop bleeding as

Question

The half-life of $^{65}$Zn is 245 days. After $x$ days, 75% of the original activity remained. The value of $x$ in days is __________ (Nearest integer).}
(Given: $\log 3 = 0.4771$ and $\log 2 = 0.3010$)

Answer 1

To understand why $FeCl_3$ is used to stop bleeding, we need to delve into the concept of coagulation, which is a process that helps in the clotting of blood to prevent excessive bleeding.

Explanation:

When there is a cut or wound, the body's natural response is to stop bleeding by forming a clot. This involves a complex series of events, including the action of platelets and the transformation of fibrinogen to fibrin, which stabilizes the clot.
$FeCl_3$, or ferric chloride, is often used as a coagulant in various processes due to the properties of ferric ions (Fe^{3+}).
The ferric ions in $FeCl_3$ can cause coagulation. These ions have a high positive charge, which helps in the aggregation of negatively charged particles or colloids present in the blood.
When $FeCl_3$ is applied to a bleeding area, the ferric ions facilitate the clumping of blood components, promoting faster clot formation.

Justification of the Options:

Option: Cl– cause coagulation - Chloride ions (Cl^-) do not play a significant role in the coagulation of blood. Therefore, this option is incorrect.
Option: Ferric ion cause coagulation - This is the correct answer as the ferric ions (Fe³⁺) in $FeCl_3$ act as a strong coagulant, promoting the blood clotting process.
Option: $FeCl_3$ dilutes blood - Dilution of blood is not the mechanism by which bleeding is stopped. This option is incorrect.
Option: Bleeding does not stop - This contradicts the clotting role of $FeCl_3$. Therefore, this option is incorrect.

In conclusion, the use of $FeCl_3$ in stopping bleeding is attributed to the coagulating property of ferric ions, which encourages clot formation by aggregating blood components. This ensures that bleeding is effectively controlled.
