Why when tested with a red litmus paper baking powder dont change the color or paper?

Baking powder is a common leavening agent used in baking. It typically contains baking soda, an acid (such as cream of tartar or monocalcium phosphate), and a drying agent (such as cornstarch). When baking powder is mixed with water, the acid and baking soda react to produce carbon dioxide gas, which causes baked goods to rise.

Red litmus paper is a type of indicator that changes color when it comes into contact with an acid. If baking powder were an acid, it would cause red litmus paper to turn pink or red. However, baking powder is not an acid, so it does not change the color of red litmus paper. Baking soda is a base. So when it comes into contact with red litmus paper, it will change its color blue.
