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 (CO2). 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.
