This answer that the solution just turns a dark colour when iodine and bicarb are mixed is just plain wrong. If you mix 900ml water with 100 ml iodine the solution turns dark red. Then add three heaped tablespoons of bicarb. Leave for 24 hours. The mixture will turn absolutely clear. If that does not work for you then add more bicarb. It works.
So what is the reaction that is taking place? Proper answer please. Lets not guess.
When baking soda (sodium bicarbonate) is mixed with iodine, a chemical reaction does not occur. Baking soda is a base and iodine is a nonpolar molecular compound, so they do not react with each other.
Chemical Change
In my science lad the mixture turned red. I don't know if it is the white colour of the baking soda making the iodine lighter or if it were a chemical reaction.
A nonhomogeneous mixture is obtained (for solids).
Nothing happens when backing soda and sand are mixed. There is no reaction.
It will most likely make the substances bubble up a lot.
Not as good as baking soda and vinegar!
Not much will happen if you mix baking soda with water. If you mix it with vinegar something will happen. Vinegar is more acidic.
Chemical, When something changes in color, it is a sign of a chemical change.
Baking powder, baking soda, or iodine.
Yes baking soda and oil can be mixed together,especially when baking.
The concentration increases. Eventually, all of the water will evaporate leaving dry baking soda behind.
