This is a basic inquiry. I'm wondering what is it in an aluminum chloride solution 20-30% that, say if it was applied to a small bleeding cut,
makes it stop bleeding immediately?
Just for your info

Yes that would be because of the aluminum ion's ability to be astringent. Most scientific/ chemistry reference volumes will state this as one of
the basic properties of hydrated aluminum compounds. Just so you know, this forum is more designed for discussing topics that we already researched.
No offense but just to let you know.

I'm sorry, but I beg to differ. This forum is designed for discussing topics related mostly to chemistry, whether fully researched, or whether
currently being researched. In fact, discussion of new upcoming topics (as long as it's got some scientific base) is encouraged.TCRN - 21-7-2004 at 13:20

I looked up the word "astringent" in the dictionary; it told me it meant styptic. I looked that up and it told me that it means that it
stops bleeding.
I think TCRN already knew it did that.
Because the aluminium 3+ ion is rather small and has a relatively large charge on it it can denature proteins by binding to them. It also acts as an
acid which has the same effect because many proteins are either acidic or basic and changing the pH will affect the overall charge on the protein
chain.
This denaturing of the soluble proteins in the blood causes it to clot in much the same way as boiling egg white makes it set.
(btw, there is a section of the forum called "beginings" for basic questions, though arguably, this was an acidic one)

unionised, probably cloric is european, astringent directly derives from latin, is a word used as it is in italian, spanish and many other languages..
you can give an idea of what it means by licking some KAl(SO4)2...chemoleo - 21-7-2004 at 18:13
