Final answer:
The conjugate acids for HSO₃⁻, F⁻, and PO₄³⁻ are H₂SO₃, HF, and HPO₄²⁻ respectively. For CO, it does not form a conjugate acid in the typical sense.
Step-by-step explanation:
To find the conjugate acid of a base, we typically add a hydrogen ion (H+) to the base. The conjugate acid will have one more hydrogen ion compared to the base and a higher positive charge (or a lower negative charge) by one unit.
- For HSO₃⁻, we add an H+ to form H₂SO₃.
- For F⁻, we add an H+ to form HF.
- For PO₄³⁻, we add an H+ to form HPO₄²⁻.
- For CO (if it refers to the neutral molecule carbon monoxide), there's a slight misconception as it is not a typical acid or base in the Brønsted-Lowry sense, but if we consider it as a metal carbonyl, we could discuss its reactivity; otherwise, carbon monoxide does not form a conjugate as acids and bases do.
