Chapter 13.6, Problem 3RC

(a)

Interpretation Introduction

Interpretation:

In the given pair of compounds, which are more likely to form ion pairs in water has to be indicated.

Concept Introduction:

A couple of oppositely charged ions are connected together by Coulomb attraction is known as ‘ion pair’.

The ion pair consists of one or more anions and cations which are held together by electrostatic forces.

Concept introduction:

The ion pair consists of one or more anions and cations which are held together by electrostatic forces.

Coulomb’s law: This law states that oppositely charges are attracts each other with a force proportional to the product of the charges and inversely proportional to the distance between the charges and likely charges repels each other.

$\text{F}\propto \frac{{\text{q}}_{\text{1}}{\text{q}}_{\text{2}}}{{\text{d}}^{\text{2}}}$

$\text{F=k}\frac{{\text{q}}_{\text{1}}{\text{q}}_{\text{2}}}{{\text{d}}^{\text{2}}}$

Where,

${\text{q}}_{\text{1}}{\text{and q}}_{\text{2}}\text{- signed magnitude of charges}$

${\text{d}}^{\text{2}}\text{-Distance between the charge}$

K - Coulomb’s law constant
