Question

name the bivalent acid radical which has two atoms groups?​

Answer 1

Answer:

The ion formed after removal of Hydrogen ion from an acid is called as Acidic Radical.

For example:

when HCl loses  H⁺  ion from acid . we get Cl⁻ which is an acidic radical -- which is monovalent.

Bivalent means the acid should lose 2 H+ ions.

example:

H2SO4 :

From H2SO4 loses 2 H⁺ ions, so we get, SO₄⁻²

Carbonic acid.

H2CO3

H2CO3 loses 2H⁺ ions we get CO₃⁻²
