उत्तर
The positive part is called the basic radical and the negative part is called the acid radical.
A compound maybe consider having –
- A positive part [e.g. metal or ammonium ion]
- A negative part [e.g. chloride, bromide, sulphate, nitrate etc.]
| Compound | Positive part - Basic Radical | Negative part - Acid radical |
| Sodium | \[\ce{Na+}\] | \[\ce{NO3-}\] |
| Ammonium | \[\ce{NH4+}\] | `"SO"_4^--` |
| Sulphate |
