Why does water when you leave it sitting around awhile in a bottle or glass get bubbles that stick to the sides and taste just a little different?
In: Chemistry
The bubbles are from dissolved gases falling out of solution. Probably nitrogen and CO2. The change in taste is a result of these gases, as well as whatever minerals were added, falling out of solution.
