Baking soda is not at all similar to tapioca starch, so you would get a very different result if you replaced one with the other. A more logical substitution for tapioca starch would be corn starch.
No. Corn starch is usually used as a thickener (for gravies, soups, puddings, etc)., whereas baking soda is used as a puffer-upper for biscuits, cookies and unleavened breads and so on. Use flour as a substitute for corn starch, and baking powder as a substitute for baking soda.
Then it wont come out good.
Because baking soda is NaHCO3 and starch is (C6H10O5). Getting starch in packs of baking soda would be like getting mincemeat in your orange juice. It's not what you're buying.
No, baking soda is not a starch. It is a chemical compound known as sodium bicarbonate, which is commonly used as a leavening agent in baking to help batters rise. Starch, on the other hand, is a carbohydrate that primarily serves as a source of energy in foods like grains, potatoes, and legumes.
No, baking soda and baking powder are not the same. Baking soda is a single ingredient (sodium bicarbonate) while baking powder is a mixture of baking soda, an acid, and a starch.

Baking powder is a "leavening agent" that makes cakes rise. Baking soda and cream of tartar together do the same job -- they react to make carbon dioxide gas. If you try to make cupcakes without either baking soda, or the combination of baking soda and cream of tartar, your cupcakes will not rise and you will get something close to cookies. Corn starch is a thickener and acts similarly to flour. If you have flour, corn starch may not be necessary.
baking soda
"Baking powder" is a leavening agent and is a mixture of baking soda (sodium bicarbonate), one or more acid salts, and a starch (usually cornstarch).
baking soda has a crystalline appearance because it is a form of salt. [edit]Duude you're doing the Mystery Powder Analysis Gizmo lol. Now I have the answer ITS B.salt you are soo right i am doing the Gizmo its annoying!
