Detailed Solution
Download Solution PDFThe correct answer is Carbon dioxide.
Key Points
- Baking powder
- When baking powder is heated or mixed in water, carbon dioxide gas is produced.
- When you add water to baking powder, the dry acid and base go into the solution and start reacting to produce carbon dioxide bubbles.
- Single-acting baking powder produces all of its bubbles when it gets wet.
- Double-acting baking powder produces bubbles again when it gets hot.
- Baking Soda
- Baking Soda, chemically known as sodium bicarbonate, is a baking ingredient that’s activated by a liquid and an acid to help with leavening or rising.
- Baking soda is used in recipes that also include an acidic ingredient, such as cream of tartar, buttermilk, or citrus juice.
- The chemical reaction when baking soda is reacted with vinegar:
- CH3COOH + NaHCO3 → H2O + CO2
