What can happen if baking soda and vinegar mix?
If one is working with equal amounts, baking soda might produce more carbon dioxide when mixed with vinegar, because baking powder is already combined with an acidic ingredient.
It bubbles up, like baking soda and vinegar
It is not toxic when drank, but it is not recommendable to do so.
You might be thinking of baking soda, which needs vinegar, buttermilk, or lemon juice to activate. Baking powder is a blend of simple chemicals, and activates with water.
Baking powder leaves more residual and "cakes" together. Corn starch is a little bigger and doesn't taste like baking powder.
