What happens when you mix baking powder with vinegar?

When you mix baking powder with vinegar, a chemical reaction occurs that releases carbon dioxide gas. This is the same reaction that makes baking powder work in baking.

Here's why:

* Baking powder contains sodium bicarbonate (baking soda), an acidic component (like cream of tartar), and a drying agent (like cornstarch).

* Vinegar is an acidic liquid.

When the acid in the vinegar comes into contact with the baking soda in the baking powder, it triggers a reaction that releases carbon dioxide gas. This gas creates bubbles in the batter or dough, causing it to rise and become light and airy.

However, the reaction happens quite quickly when you mix baking powder and vinegar directly. This means you won't get the same light and airy texture you would achieve by using baking powder in a recipe. The bubbles will form and dissipate too quickly before they have a chance to make the batter rise.

In short, mixing baking powder and vinegar creates a chemical reaction that releases carbon dioxide gas, but it's not a practical method for baking. It's best to use baking powder according to the instructions on the package.
