The science behind double acting baking powder
Today’s Video of the Day from the American Chemical Society describes the science behind double acting baking powder.
Baking powder always contains at least one solid acid as well as a solid base – usually baking soda – which react when water is added to produce bubbly carbon dioxide.
A double acting baking powder will react and create gas bubbles once when added to a liquid, and then a second time when exposed to heat.
