Why bubbles appear when you open a bottle of soda but not mineral water?

When you open a bottle of soda, the pressure inside the bottle is suddenly released, causing the dissolved carbon dioxide gas to come out of solution and form bubbles. This is because carbon dioxide is more soluble in water at higher pressures. When the pressure is reduced, the gas is less soluble and comes out of solution.

Mineral water, on the other hand, typically has a lower concentration of carbon dioxide gas dissolved in it than soda. This is because the carbon dioxide gas in mineral water is naturally occurring, while the carbon dioxide gas in soda is added artificially. As a result, mineral water does not produce as many bubbles when opened as soda does.

In addition, the temperature of the water can also affect the amount of bubbles that are produced. When water is cold, it can hold more carbon dioxide gas in solution than when it is warm. This is why soda that is cold produces more bubbles than soda that is warm.
