Question : Which gas is used by chemical leaveners, such as baking powder and baking soda, to lighten and aerate baked goods?
Option 1: Nitrogen
Option 2: Carbon dioxide
Option 3: Helium
Option 4: Hydrogen
Correct Answer: Carbon dioxide
Solution : The correct answer is Carbon dioxide.
The gas used by chemical leaveners like baking powder and baking soda to lighten and aerate baked goods is carbon dioxide (CO 2 ). During baking, these leavening agents release carbon dioxide gas, which gets trapped in the batter or dough, causing it to rise and create a light and airy texture in the final baked product.
