Chapter 19, Problem 91IAE

Interpretation Introduction

Interpretation:

Whether the color of solution appears blue or not if ${\left[\text{Cu}{\left({\text{NH}}_{\text{3}}\right)}_{\text{4}}\right]}^{2+}$ is detected at lower concentration of $1\times {10}^{-5}\text{ M}$.

Concept introduction:

In an electrochemical cell, chemical change is used to produce electricity. It uses electricity to produce a non-spontaneous reaction.

Electrolysis is the process in which a non-spontaneous reaction is driven by the application of electric energy.

The half-cell reaction with the lowest reduction potential reduces 1^st in electrolysis process.

$1{\text{ mol e}}^{-}=96485\text{ C}$
