What is baking powder on a pH scale?

Baking powder is alkaline on the pH scale.

Here's why:

* Baking powder contains sodium bicarbonate (NaHCO3), which is a base. Bases have a pH greater than 7.

* Sodium bicarbonate reacts with an acid (usually tartaric acid or cream of tartar) when mixed with water. This reaction releases carbon dioxide gas, which is what makes baked goods rise.

* The reaction produces a solution that is slightly alkaline, typically with a pH around 8 or 9.

While the exact pH can vary depending on the specific baking powder formula, it's generally considered to be alkaline.
