I suspect that re-arangement of molecular structures has influenced the refrationans of light waves?????   Is that clumsy supposition in the ball park Caleiasseia?


Your screen name is difficult, Please allow me to refer to you as Ms. C hereafter.  In any case, your posts are stimulating.

There are two reactions generating I^- ions, one fast and one slow, and similarly, two reactions consuming the I^- ions and converting them to free iodine. As long as the system is far from equilibrium, the reactions will continue, acting as feedback loops for each other. Arrange for different transition metal ions to be present during the I^- generation phase, and the resulting iodide salts are strongly coloured. There's also starch in there, which of course forms a complex with free iodine that's a deep blue colour.

I find inorganic chemistry much more intimidating than organic chemistry, but I understood your clear explanation.

Sorry about the Ms/Mr thing C..

Ever vigilant Tank forces me to pay closer attention

He's got long hair so it's an understandable mistake

Here is a legitimate fun science video.  It is fun because Neil D, Tyson is animated as usual.   This guy is an extemporaneous speaker of remarkable ability.  This is a Q and A session.   Along about 14 minutes in, one of the questions is about religion.  He answers with class and respect for the questioner.   He also defeats the faith concept politely but decisively.

Worth the twenty minutes or so.  (well at least it is for me)      https://www.youtube.com/watch?v=bd993w3syBM

That's great! I love these song parody videos.
