Which of the following aqueous solutions will be basic?
Correct answer: B. Na₂CO₃
- A. NaCl
- B. Na₂CO₃
- C. Na₂SO₄
- D. FeCl₃
Explanation
Sodium carbonate (Na₂CO₃) is the salt of a weak acid (H₂CO₃) and a strong base (NaOH). The carbonate ion (CO₃²⁻) hydrolyzes water to produce OH⁻ ions, making the solution basic.
