Question

Name 20 monovalent acid radicals

Answer 1

Answer:

The ion formed after removal of Hydrogen ion (H⁺ ion) from an acid is called acid radical. Ex: When HCl loses H⁺ ion, it forms Cl⁻ which is an acid radical. Following given the list of acidic radicals.

Acid Acid radical

HCl Cl⁻

HNO₃ NO₃⁻

CH₃COOH CH₃COO⁻

H₂SO₄ SO₄⁻²

H₂CO₃ CO₃⁻²

HBr Br⁻

HF F⁻

HI I⁻

H₃PO₄ PO₄⁻³

HClO₄ ClO₄⁻

HNO₂ NO₂⁻ The ion formed after removal of hydroxide ions (OH⁻ ions) from a base is called basic radical. Ex: When NaOH loses OH⁻ ion, it forms Na⁺ which is a basic radical.

Base Basic radical

NaOH Na⁺

KOH K⁺

LiOH Li⁺

Mg(OH)₂ Mg⁺²

Ca(OH)₂ Ca⁺²

RbOH Rb⁺

CsOH Cs⁺

Ba(OH)₂ Ba⁺²

Fe(OH)₃ Fe⁺³

Cu(OH)₂ Cu⁺²

Zn(OH)₂ Zn⁺²

Acid radical + Basic radical → Salt

Acid radical Basic radical Salt

Cl⁻ Na⁺ NaCl

NO₃⁻ K⁺ KNO₃

CH₃COO⁻ Li⁺ CH₃COOLi

SO₄⁻² Mg⁺² MgSO₄

CO₃⁻² Ca⁺² CaCO₃

Br⁻ Rb⁺ RbBr

F⁻ Cs⁺ CsF

I⁻ Ba⁺² BaI₂

PO₄⁻³ Fe⁺³ FePO₄

ClO₄⁻ Cu⁺² Cu(ClO₄)₂

NO₂⁻ Zn⁺² Zn(NO₂)2
