It does not. -.-
baking soda change color because of the heat it will get cook because when you first but it in it is a diffrent color
What color change do you see when you added ammonia to mustard?
pretty sure its a chemical change.
No color change is there...

Phenol red is a pH indicator. The baking soda is not changing color, but the phenol red is.
Assuming that the cookies have flour, eggs, sugar, and a touch of baking soda or baking powder. The heat will: > Cause the protein in the eggs to firm up ( it is much like polymerization of a plastic), This is what holds the cookie together > The sugar and starch will react with oxygen in the air...this is what gives the cookie a brown color ( too much oxidation and you have burnt cookies!) The baking powder or baking soda ( depending on recipe) will cause the cookie to rise by releasing carbon dioxide....the same gas in soda. Baking soda will need something acidic (tart tasting = acidic) to start the reaction..like buttermilk. Baking powder only needs the presence of a liquid. Double acting baking powder releases carbon dioxide when it comes in contact with a liquid and then again when exposed to heat. A little thought about this will indicate that if you let a batch of cookie dough sit around all (or at least most) of the carbon dioxide will work its way out and you will have flatter cookies than if you made them right away.
you would expect a color change in oil of wintergreen because it has an OH group added to the FeCl3 which causes a purple color
Chemical, When something changes in color, it is a sign of a chemical change.
Yes. They can. The clues of a chemical reaction are production of a gas, change in temperature, color change, production of a precipitate. If you take either baking soda or baking powder, and you add them to vinegar they both form bubbles in a chemical reaction.
it turns red
The color does not change unless an indicator such as litmus or phenolphthalein is being used. If litmus the color change is blue to red If phenolphthalein the change is red to colorless
