Baking soda’s chemical equivalent is sodium bicarbonate. In contrast, baking powder’s chemical equivalent is a mixture of sodium bicarbonate. It is a weak acid like monocalcium phosphate or an aluminium compound. It is also a carrier powder, sometimes corn-starch.
Both baking soda and baking powder are chemical leavening agents used in baking. Baking soda also has a few other uses, like alkalising water for bagels or pretzels, but baking powder, mostly for baking.
Baking powder is baking soda along with an acid such as tartaric acid used as a raising agent in baking.
Baking soda and baking powder are both essential in the kitchen. Cakes, brownies, cookies, cornbread, shortening bread, and any quick bread depend on them.
Baking powder is a blend of baking soda, cream of tartar, and corn-starch. The added acidity from the cream of tartar helps baked goods rise, and I’m not sure what the corn-starch is for but could imagine that it’s to keep it from clumping by moderating moisture.
Baking soda is used for baking, but usually, you need to have something acidic in the recipe to help it create a good rise. It can also be used for cleaning, compresses and soaks, laundry, tooth cleaning, as an antacid, to make science project volcanoes, as an odour absorber to keep refrigerators from getting stinky, etc.
Baking powder contains baking soda. It is a mixture of baking soda, cream of tartar (a dry acid), and sometimes corn-starch. These days, most baking powder sold is double-acting, which implies that the first leavening occurs when baking powder gets wet– like when you mix the dry and wet ingredients in the recipe. (This is why you cannot prepare some batters ahead of time to bake later– because the baking powder has already been in activation.) The second leavening happens when the baking powder is heated.
Baking soda is simple sodium bicarbonate while baking powder is a mixture of baking soda and acid in powder form. Both are used in cooking to form carbon dioxide bubbles in a dough or batter (leavening). Baking powder is applied when there is not enough natural acid in the dough or batter to react with baking soda. For cleaning, baking soda is generally better. Baking Soda can be used as a paste with water or mixed with vinegar as a cleaning solution, by itself as an odour neutraliser and of course in baking but not as a leavening agent. To prevent clumping from moisture Baking powder is mixed with corn-starch. Those to agents combined to give you baking powder, and to many me included it changed everything. It was invented in Queen Victoria’s time by a pharmacist. Baking soda is sodium bicarbonate. It is used as a raising agent with an acidic liquid (e.g. buttermilk) in many recipes. It also fits for use in cleaning, as a toothpaste, and remedy for acid indigestion.
The similarity between baking soda and baking powder
Baking powder and baking soda have a lot in common. They’re both types of chemical leaveners, meaning they generate gas during the mixing and baking of a batter or dough that “raises” or aerates the baked good. So both are used in baking. Only baking soda is used for cleaning because it is an acid. Baking powder is an acid and base.
We use baking soda for several things, including cleaning, de-odorising items such as drains, refrigerators, freezer, and wastebaskets. It can be used to brush teeth, too. It’s great to have in hand.
Differences between the Baking soda and the Baking powder
- Baking soda is the active chemical agent sodium bicarbonate whereas Baking powder is just that, a powder blend of baking soda and starch (wheat).
- Baking soda is used for cleaning since it’s alkaline or basic and hence a relatively high pH in water. Still, it’s not a very strong alkali in terms of a chemical reaction and baking powder, on the other hand; its starch acts. The starch acts as a diluent allowing easy weighing and mixing and hence a fair distribution without clumping within a formulation.
- Baking soda is sodium bicarbonate, and it needs both an acid and a liquid to activate and make baked goods rise. In contrast, the Baking powder is sodium bicarbonate with an acid added to it, so it is used to make baked goods rise when there are no other acid ingredients in the recipe.
- Baking powder makes things rise while Baking soda changes the PH.
- The main distinction in their use is that baking soda requires acid for its leavening action (to make it fizz), while baking powder already has the acid.
