Question

Identify the acid and basic radicals in the given salt

Answer 1

Explanation:

For example, when NaOH dissociates to give Na+ and OH- ions, Na+ has lost an OH-, hence is called the basic radical. Acidic radical are anions which are negatively charged. For example: SO4 2-, NO3¯ , etc. Basic Radicals are cations which are positively charged.

Answer 2

Question:

State the difference between: acid radical and basic radical

Answer:

Radical ions are free radicals with an electrical charge. In organic chemistry, they are primarily viewed as reactive intermediates. These ions may be negatively or positively charged. It can be either basic or acidic depending on its charge.

Acid Radical:

• The ionic portion of an inorganic salt that arises from the acid during the neutralization reaction is known as an acid radical.
• It has a negative charge and is referred to as an anion.
• Most often, an acid radical is created by removing a hydrogen ion from an acid.
• For instance, the removal of a hydrogen ion from hydrochloric acid results in the production of the anion acidic radical which is a chloride radical.
• Anionic radicals like chloride, sulphate, bromide, etc. are examples of acidic radicals.

Basic Radical:

• The ionic component of an inorganic salt that is produced by the base during the neutralisation reaction is known as a basic radical.
• It is referred to as a cation and is positively charged.
• Most often, the removal of hydroxyl ions from a base results in the formation of a base radical.
• For instance, the production of the sodium radical, a cation basic radical, results from the elimination of hydroxide ions from sodium hydroxide (caustic soda).
• Cationic radicals like sodium, zinc, potassium, etc. are examples of basic radicals.

Consider a salt solution that contains sodium chloride (NaCl) and magnesium sulphate (MgSO₄).

It has the following radicals:

• NaCl ⇒ Na⁺ + Cl⁻.

Here Na⁺ is the acidic radical and Cl⁻ is the basic radical.

• MgSO₄ ⇒ Mg²⁺ + SO₄²⁻

Here, Mg²⁺ is the acidic radical and  SO₄²⁻ is the basic radical.
