Answer to Question #52894 in Physical Chemistry for fiok

Question

Will PH3 AND HCl react and create white smoke like NH3 and HCl react and make NH4Cl?

i have a question regarding this topic. at two end point of a 100 cm cylinder NH3 AND HCl are placed. when they started to diffusion at which place a white smoke of NH4Cl will be created?

if PH3 was used instead of NH3 will their any change in the place where the smoke was created?
now i am not sure Will PH3 AND HCl react at here or normally?

Answer 1

The gases start to move immediately after you place their sources (wadding) inside. They are simultaneously diffusing to the center of the tube. As compounds move slowly, NH4Cl are formed as a white crystals at the place somewhat shifted from the center to the HCl source.

The PH4Cl is unstable even at low temperature. So at the normal conditions PH3 does not react with HCl at all.
