Yup, you are right (Le Chatelier's principle take an action here) Thank you!
But, anyway, the experiment is colorful

Two days ago I make one ordinary experiment: Iodine solution and Ammonia
I've got a black precipitate, then I decided to put in the jar Na2CO3 solution. Then I added CH3COOH.
After that reaction NaHCO3 + CH3COOH → CH3COONa + H2O + CO2, the whole thing became ORANGE!?
Have any one have an idea what have happend? I am pretty sure that there is hydroiodic acid (HI), but what else and the main question: WHY IT'S ORANGE?
