Xenomorph Blood is Hydrogen fluoride

The xenomorph blood is apparently Hydrogen fluoride, according to an intel file mentioned in Alien: Sea of Sorrows, page 147.

It takes place in 2497 if I'm not mistaken.

So we can dream about a lot of Alien movies between 2104 and 2497. :)

Interesting find! I am not familiar with the compound. Based on the periodic table, I believe fluorine is in the same group as chlorine?  I have noticed inconsistencies with how that blood reacts throughout the series LOL! Aliens comes to mind although I love it nonetheless.

All said, if it is a strong acid for blood, an effective weapon would seem to be one that could penetrate the body with a basic solution to neutralize the acid? Gotta brush up on the ol' chemistry classes. I do know that experimenting with hydro chloric acid and water as a kid yielded nasty results. Boring summer days with swimming pool water maintenance duties- what could go wrong lol!

I work with HF, It is friggin nasty shit, but Alien blood it is not.

Hydrofluoric Acid is ridiculously corrosive to organics and metals, but is considered a 'weak acid' due to its low dissociation constant.

Essentially it penetrates skin and flesh, strips calcium from the bones then works it way back. If you've watched Breaking Bad season 1 where they dissolve the body in a bathtub slowly over a week until its a goopy liquid mess.....HF. 

Wipe or wash it off and it keeps burning!! Calcium Gluconate is needed to stop the reaction. Nasty, nasty shit!! 

Hydrofluoric Acid also attacks silicates, which seems to go against the chitinous exoskeleton of the Xenos. 

Science Bitches!
