it is kind of like flour and even looks like flour.
No you can't. Baking powder is a leavening agent while cornstarch is a thickening agent. The same applies to baking soda, which will also make doughs "rise," whereas cornstarch will not.

Baking soda is an alkaline compound that can only be separated chemically.Baking powder however is a mixture of baking soda and an inert starch, usually cornstarch. Cornstarch absorbs moisture in the baking powder, prolonging shelf life and preventing premature reactions in the baking soda. Baking soda and cornstarch can be separated using conventional means, as it is not a compound.
cornstarch
No....try baking soda
Sodium bicarbonate (baking soda), sodium bitartrate, and cornstarch polymer
sure, but why do you want to use it. Cornstarch is used as a thickener, and is activated when reaching waters' boiling point. Not sure if this answers your question or not. If I am to guess, you are wanting to substitute the cornstarch for baking soda/baking powder. Again, I may be wrong about why you want to use it. As far as I know, cornstarch doesn't function like baking powder/soda in baking. The two act as leavening agents (creating air bubbles in baked goods), if this is your line of thinking, then cornstarch would not substitute. Hope this helps! Happy cooking, I love waffles!
you can use cornstarch
flour
The proper substitution for baking powder is half baking soda and half cream of tartar. They both have leavening properties. If you don't have cream of tartar available, I guess I would go toward 2/3 - 3/4 baking soda and the rest cornstarch.
They are certainly not the same thing, but it depends on your purpose if you can substitute them or not! If you are cooking and the recipe calls for baking soda, borax can definitely notbe used! But if you are using baking soda for cleaning, borax is also a good cleaning agent.
Baking powder contains a combination of baking soda, an acid like cream of tartar and a moisture absorber like cornstarch. it just helps lift up what ever it is you are baking
