When mixed baking soda and vinegar yield?

Mixing baking soda (sodium bicarbonate) and vinegar (acetic acid) results in a chemical reaction that produces carbon dioxide gas, water, and sodium acetate. The reaction can be represented as:

NaHCO3 (sodium bicarbonate) + CH3COOH (acetic acid) → CO2 (carbon dioxide) + H2O (water) + CH3COONa (sodium acetate)

The carbon dioxide gas causes a fizzing reaction and creates bubbles. This is why baking soda and vinegar are commonly used as leavening agents in baking, helping to make baked goods rise. The reaction also produces a slightly salty flavor due to the formation of sodium acetate.
