Question: what is the chemical difference between washing soda and baking powder?
Answer: The difference between baking soda and washing soda is water and carbon dioxide. Seriously. Baking soda's chemical makeup is NaHCO3 (1 sodium, 1 hydrogen, 1 carbon, and 3 oxygen molecules). Washing soda's chemical makeup is Na2CO3 (2 sodium, 1 carbon, and 3 oxygen molecules).
