If it was possible, what would a sea made of liquid state Iodine look like? How would it smell?

From my research, I've seen people saying its liquid state is somewhat "invisible" since it generates a lot of vapor around it, so it looks always gassy. Also, I suppose it would have a dark red color, but I'm not sure since solid Iodine seems something between black and purple.

    $\begingroup$ It'd look, smell, and act like iodine. Iodine is liquid all the time, and a sea of it is actually possible if you get enough of it. I haven't smelled iodine, or really messed with it, so i can't give a true answer. $\endgroup$ – moonheart08 Nov 15 '18 at 16:58

    $\begingroup$ @moonheart08: Iodine is a solid in normal conditions. It melts at 114° C. $\endgroup$ – AlexP Nov 15 '18 at 17:40
  • $\begingroup$ @AlexP: I think the OP means the sublimation of iodine at room temperature will result in different properties in the liquid phase $\endgroup$ – nzaman Nov 15 '18 at 18:43

According to this paper, iodine can be melted under relatively controlled conditions. Iodine is classically described as a sublimating solid (skips from solid to gaseous state).

The accompanying video shows very clearly that solid iodine crystals can be melted into a very dark inky-purpley-black liquid.

Melting iodine

So I guess the answer is: if you have a sufficiently stable temperature within the planet, an ocean of iodine will look like very dark, deep, deep purple-black ink and it will smell like iodine. "Mediciney".

    $\begingroup$ Yeah,it will be close to black liquid, with clouds of violet over it. And sure not a place life can survive. Why it did not react with something? $\endgroup$ – Artemijs Danilovs Nov 15 '18 at 20:39
