Soda water reaction with baking soda?

The reaction between soda water and baking soda (sodium bicarbonate) produces carbon dioxide gas, water, and sodium carbonate. The chemical equation for this reaction is:

NaHCO3(aq) + H2O(l) + CO2(g) → Na2CO3(aq) + H2O(l)

When baking soda is added to soda water, the carbonic acid in the water reacts with the baking soda to form carbon dioxide gas. This gas causes the fizzing and bubbling that is characteristic of this reaction. The sodium carbonate that is produced is a white powder that can be used as a cleaning agent or as a water softener.

This reaction is also used in the production of baking powder, a leavening agent that is used in baking. When baking powder is added to a batter or dough, it reacts with the water and other ingredients to produce carbon dioxide gas, which causes the batter or dough to rise.
