Comment tester l'acide hypophosphorique

[evangelium]

Bonjour, je me demande comment tester la présence d'acide hypophosphorique pour être sûr que j'ai du vrai hp et pas du faux. Peut-être le test tlc ?

Bonjour, la TLC est possible mais je recommanderais d'effectuer un titrage avec une solution d'iode.

I don't know how definitive this is but I knew folks that would stick a pocket knife in it, pull it out and touch it with a flame. If its hypo it burns like its gas and kinda sparks lightly but its the smell that is produced that confirms what they've got. Try it sometime. Kinda analog but if someones just selling something fake at least you'll know.
