If you've ever found yourself stumped while baking, wondering what the difference is between baking soda and baking powder and which one you need, we've got all you need to know. While both are common cooking ingredients, there are actually a number of ways you can use baking soda in your home – including cleaning everything from your teeth to your oven!

What is baking soda?

Baking soda is another name for sodium bicarbonate, which may also be known as bicarbonate of soda. This white powder is a mixture of sodium and hydrogen carbonate, and is most commonly used for baking cakes or soda bread. Bicarbonate of soda is alkaline, so when it is mixed with acid – such as milk – it creates carbon dioxide, causing the mixture to expand before it's replaced with air. Hence, helping to make your cake rise!


What is the difference between baking soda and baking powder?

While baking soda is another name for sodium bicarbonate, baking powder is actually made up of various ingredients, including sodium bicarbonate and a mix of cream of tartar and a filler like cornflour, which absorbs any moisture. It is used to make similar foods as sodium bicarbonate, but because baking powder is an acid, you generally only need to add water to it for the same reaction.
