In chemistry, this is often the indication that a gas is being produced or release in a liquid. Here are some examples:
If Sodium hydrogen carbonate is dropped into a dilute aqueous acid, bubbles of Carbon dioxide will be formed.
Carbon dioxide bubbles can also be seen when a soda is opened and the carbonic acid decomposes into Carbon dioxide and water.
During the electrolysis of water, bubbles of Oxygen gas can be seen at one electrode and those of Hydrogen gas at the other.
