Chapter 24, Problem 53IAE

Interpretation Introduction

Interpretation:

A solution is formed by the 1.00M NH₃ and 1.00M [Cu(NH₃)₄]2+ in which the electrode of copper, Cu is immersed. If the voltage value of standard hydrogen cathode is +0.08V then the value of formation constant K_f [Cu(NH₃)₄]2+ is to be determined.

Concept introduction:

The value of $E°$ can be calculated as follows:

$E°=E{°}_{cathode}-E{°}_{anode}+E{°}_{formation}$

Nernst equation is represented as follows:

$\log K_f=\frac{nE{°}_{formation}}{0.0592}$

Here, n is number of electrons transferred in the reaction.
