Jak testovat kyselinu hypofosforečnou

[evangelium]

Ahoj, zajímalo by mě, jak mohu otestovat přítomnost kyseliny hypofosforečné, abych si byl jistý, že mám pravou hp, ne falešnou. Možná tlc test ?

Dobrý den, TLC je možná, ale doporučil bych provést titraci roztokem jódu.

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.
