Question

an acid radical of valency one​

Answer 1

Acid radical of valency one are as follows:-Cl-, NO3-,CH3COO-, Br-, F- and I-.

• Acid radical is a ion formed after a removal of Hydrogen ion (H+) from an acid is called acid radical.

• It is generally a non metal.

• For example, in HCl. When HCl is dissolved in water, it dissociates into H+ and Cl- ions.
• The Cl- has lost H+, hence Cl- is the acid radical.
