What is the difference between baking soda and baking powder? how are both of them different from each other?

i have a school project due tommm. and i cant find anything online about how baking soda and baking powder differ to each other!





answers greatly appreciated!! (easy 10 points if logical)What is the difference between baking soda and baking powder? how are both of them different from each other?
both are used for baking, but baking powder is used primarily for baking bread, as the acid salt will help the yeast rise. Baking soda is used to cook pancakes, waffles, etc., because baking soda will may those goodies rise which is not how to properly cook, plus it acts as a teeth cleaner, and anti heartburn medicine when mised with waterWhat is the difference between baking soda and baking powder? how are both of them different from each other?
Both baking powder and baking soda are chemical leavening agents that cause batters to rise when baked. The leavener enlarges the bubbles which are already present in the batter produced through creaming of ingredients. When a recipe contains baking powder and baking soda, the baking powder does most of the leavening.





The baking soda is added to neutralize the acids in the recipe plus to add tenderness and some leavening.





Baking powder consists of baking soda, one or more acid salts (cream of tartar and sodium aluminum sulfate) plus cornstarch to absorb any moisture so a reaction does not take place until a liquid is added to the batter. Most baking powder used today is double-acting which means it reacts to liquid and heat and happens in two stages. The first reaction takes place when you add the baking powder to the batter and it is moistened. One of the acid salts reacts with the baking soda and produces carbon dioxide gas.





The second reaction takes place when the batter is placed in the oven. The gas cells expand causing the batter to rise. Because of the two stages, baking of the batter can be delayed for about 15-20 minutes without it losing its leavening power.





Too much baking powder can cause the batter to be bitter tasting. It can also cause the batter to rise rapidly and then collapse. (i.e. The air bubbles in the batter grow too large and break causing the batter to fall.) Cakes will have a coarse, fragile crumb with a fallen center. Too little baking powder results in a tough cake that has poor volume and a compact crumb.








Baking soda, also known as sodium bicarbonate or bicarbonate of soda (alkali) is about four times as strong as baking powder. It is used in recipes that contain an acidic ingredient (e.g. vinegar, citrus juice, sour cream, yogurt, buttermilk, chocolate, cocoa (not Dutch-processed), honey, molasses (also brown sugar), fruits and maple syrup). Baking soda starts to react and release carbon dioxide gas as soon as it is added to the batter and moistened. Make sure to bake the batter immediately.





Baking soda has an indefinite shelf life if stored in a sealed container in a cool dry place. Too much baking soda will result in a soapy taste with a coarse, open crumb. Baking soda causes reddening of cocoa powder when baked, hence the name Devil's Food Cake.
