Answer:
Baking powder and baking soda both are leavening agents, which means they help baked goods to rise. They aren't the same chemical, but you can substitute one for another in recipes.
Step-by-step explanation:
You need to use two to three times more baking powder than baking soda. The extra ingredients in baking powder will affect the taste of whatever you are making, but this isn't necessarily bad.
1.Ideally, triple the amount of baking powder to equal the amount of baking soda. So, if the recipe calls for 1 tsp. of baking soda, you would use 3 tsp. of baking powder.
2.Another option is to compromise and use twice the amount of baking powder as baking soda (add 2 tsp. of baking powder if the recipe calls for 1 tsp. of baking soda). If you choose this option, you might wish to omit or reduce the amount of salt in the recipe. Salt adds flavor but it also affects rising in some recipes.
