Reaction of baking soda and lemon juice?

The reaction between baking soda (sodium bicarbonate, NaHCO3) and lemon juice (citric acid, C6H8O7) produces carbon dioxide gas (CO2), water (H2O), and sodium citrate (Na3C6H5O7). The overall reaction can be represented by the following equation:

3NaHCO3 + C6H8O7 → 3CO2 + 3H2O + Na3C6H5O7

When baking soda and lemon juice are mixed, the sodium bicarbonate and citric acid react to form carbonic acid (H2CO3), which is an unstable compound that quickly decomposes into carbon dioxide gas and water. The carbon dioxide gas bubbles up and causes a fizzy reaction. The sodium citrate produced in the reaction is a salt that is soluble in water and has a slightly sour taste.

The reaction between baking soda and lemon juice is often used in baking to create a leavening effect. When the mixture of baking soda and lemon juice is added to a batter or dough, the carbon dioxide gas that is produced causes the batter or dough to rise, resulting in a lighter and fluffier texture.

This reaction is also used in a variety of cleaning applications. The carbon dioxide gas bubbles can help to loosen dirt and grime, and the citric acid can help to remove stains.
