Study Notes
Formulas of Acidic Radicals
Acidic radicals are ions that, when combined with a hydrogen ion (H+), form an acid. Here are some common acidic radicals and their formulas:
Monatomic Acidic Radicals
- Chloride (Cl-)
- Bromide (Br-)
- Iodide (I-)
- Fluoride (F-)
Polyatomic Acidic Radicals
- Sulfate (SO42-)
- Nitrate (NO3-)
- Phosphate (PO43-)
- Carbonate (CO32-)
- Acetate (CH3COO-)
- Oxalate (C2O42-)
Important Notes
- When acidic radicals combine with a hydrogen ion (H+), they form an acid. For example, chloride (Cl-) combines with H+ to form hydrochloric acid (HCl).
- Acidic radicals can also combine with metal ions to form salts.
