Baking soda is referred to a sodium bicarbonate. Once it is dissolved in water it separates into sodium. When Baking soda and vinegar are combined, it makes a fizzing reaction. This is because hydrogens from the vinegar mix with the bicarbonates from the baking soda to form a new chemical named carbonic acid. Carbonic acid immediately falls apart into carbon dioxide and water. This process is referred as a decomposition reaction. The bubbles you see from the reaction come from the carbon dioxide escaping the solution that is left. Carbon dioxide is heavier than air. This makes it flows out of the volcano very smoothly. Afterwards, you are left with a dilute solution of sodium in water.
