Iodine does not react with baby powder. Baby powder is usually made of talc or cornstarch, which are inert substances and do not participate in chemical reactions with iodine.
Aluminum powder can react with iodine to form aluminum iodide. This reaction is exothermic and can produce purple fumes of iodine vapor.
My friend is coky I need to know a white powder substance that does not react with an acid
Baby powder, or talcum powder, is starchy in composition. When combined with iodine, the powder reaction will be a change in color to a dark blue, purple, or blackish hue depending on the amount used.
When iodine and borax are mixed, they do not react chemically. Both substances will remain as separate entities in the mixture. Iodine is a purple-black solid, while borax is a white crystalline powder.
If you do not have cream of tartar, baking powder will work just as well, or better. If the recipe calls for both cream of tartar and baking soda, leave out the soda if you use baking powder - it already has soda in it.
Baking powder is a 1:3 ratio of baking soda to cream of tartar. You cannot just substitute cream of tartar for baking powder - you also need the baking soda.
Baking powder is made by combining an acid (like cream of tartar) with a base (like baking soda) and a starch (like cornstarch). These ingredients react to create carbon dioxide gas, which helps baked goods rise.
Citric acid does not have a specific color in iodine. Iodine is used to detect the presence of starch, not citric acid. Citric acid typically appears as a white, crystalline powder and is not known to react with iodine in a way that produces a visible color change.
Baking powder can be made without cream of tartar by combining baking soda with an acidic ingredient like lemon juice or vinegar. This mixture can be used as a substitute for commercial baking powder in recipes.
Baking powder is baking soda with cream of tartar added to it.
Cream of tartar has an indefinite shelf life. As long as it is still powder, it is fine to use.
