Chapter 8, Problem 8.BE

Interpretation Introduction

Interpretation:

The activity of ${\left({\text{C}}_{\text{3}}{\text{H}}_{\text{7}}\right)}_{\text{4}}{\text{N}}^{\text{+}}$ ion has to be calculated.

Concept introduction:

Activity of species:

The activity value of any species is obtained by multiplying its concentration with its activity coefficient.

$\begin{array}{l}\text{For}\text{a}\text{species}\text{C, the}\text{activity}\text{is}\text{given}\text{by}\\ {\text{A}}_{\text{C}}\text{=}\left[\text{C}\right]{\text{γ}}_{\text{C}}\\ \text{where,}\\ \text{A}\text{-}\text{Activity}\\ \left[\right]\text{-}\text{Concentration}\\ \text{γ}\text{-}\text{Activity}\text{coefficient}\end{array}$
