yesterday my friend gave me a beautiful cut on my palm and as nature's rule blood .... my teacher advised me to apply FeCl3 an it really works . i don; know how ? please suggest me an appropriate ans .

 

thanks:eyebrow:

According to the MSDS of that chemical, it's corrosive and painful, so it's probably not a good idea to apply to wounds. The clotting effect is probably just due to the powdery nature of the substance giving the platelets something to hold onto and form a clot faster.

thanks

And i don't think so that was because of adsorption because then any finely divided powder (if accepted by body immunity ) can act as blood coagulant . is it so ?

Yep, pretty much any sort of powder will help clot blood. Or even non-powders that have enough absorbancy to draw out the fluid and leave a mass of platelets to start the clot. That's why little scraps of toilet paper stop the bleeding from shaving cuts.

It's also fairly acidic so it may goagulate proteins in the blood.

i think it is not because of acidic nature of FeCl3 because i added to drop of dil. HCl to 5 drops of blood and i hadn't observed any change .
