Lab Sublimazione dello iodio

Abbiamo provocato la sublimazione di alcune scaglie di I2(s) metallico, mettendole in una beuta chiusa con tappo di gomma e posando la beuta su una piastra riscaldante.

La sublimazione ha mostrato che i vapori di iodio hanno il colore viola.

In seguito al raffreddamento i vapori di iodio hanno subito il brinamento che abbiamo notato vedendo scomparire il colore viola dei vapori e vedendo comparire tantissimi puntini solidi metallici sulle pareti della beuta.
