Which polyatomic ion is commonly found in baking soda?
- A Bicarbonate (HCO₃⁻)
- B Hydroxide (OH⁻)
- C Nitrate (NO₃⁻)
- D Sulfate (SO₄²⁻)
That's Correct!
It's Wrong!
Bicarbonate is a crucial polyatomic ion that acts as a buffer in biological systems, particularly in maintaining the pH balance of blood and other fluids. In baking, bicarbonate reacts with acids to produce carbon dioxide gas, causing dough to rise. This property makes it a key ingredient in recipes requiring leavening agents. Furthermore, bicarbonate ions play a significant role in regulating acid-base homeostasis in the human body.
