Final answer:
Baking soda is sodium bicarbonate (NaHCO3) and does not contain aluminum. The correct answer is 'b) Sodium,' since that is one of the elements in sodium bicarbonate. the correct answer to the question is "b) Sodium
Step-by-step explanation:
The primary component in baking soda is sodium bicarbonate (NaHCO3). When we mention "baking soda (bs) aluminum-free," we are referring to a product that does not contain aluminum. None of the basic ingredients in baking soda are aluminum-based compounds. since sodium bicarbonate is comprised of sodium (Na), hydrogen (H), carbon (C), and oxygen (O). Aluminum is not part of its chemical makeup.
In contrast, products such as sodium aluminosilicate or aluminum hydroxide do contain aluminum and are different from sodium bicarbonate. It's important to note that some baking products may contain ingredients like aluminum phosphate (for example, in baking powder), but this is not the case with pure sodium bicarbonate. Consequently, the correct answer to the question is b) Sodium.
