Final answer:
The acid with the formula H₂CO₃ is called carbonic acid. The two anions derived from carbonic acid are the carbonate ion (CO₃²⁻) and the bicarbonate ion (HCO₃⁻).
Step-by-step explanation:
The acid with the formula H₂CO₃ is called carbonic acid. The two anions derived from carbonic acid are the carbonate ion (CO₃²⁻) and the bicarbonate ion (HCO₃⁻).
The carbonate ion (CO₃²⁻) is derived from carbonic acid by losing one hydrogen ion (H⁺). The bicarbonate ion (HCO₃⁻) is derived from carbonic acid by losing two hydrogen ions (2H⁺).
Therefore, the formulas of the two anions derived from carbonic acid are CO₃²⁻ and HCO₃⁻. The carbonate ion (CO₃²⁻) and the bicarbonate ion (HCO₃⁻) are named as follows:
- Carbonate ion (CO₃²⁻)
- Bicarbonate ion (HCO₃⁻)
