Chapter 17, Problem 17.29P

(a)

Interpretation Introduction

Interpretation:

The graph of current polarogram for given solution of copper ion has to be sketched.

Concept introduction:

In the electrochemical reactions the relation between current and voltage is noted and this technique is called voltammetry.  A graph which represents current Vs voltage is called voltammogram.

(b)

Interpretation Introduction

Interpretation:

The graph of current polarogram for Cu2+ ion has to be sketched.

Concept introduction:

Voltammetry:

In the electrochemical reactions the relation between current and voltage is noted and this technique is called voltammetry

Polarography:

Voltammetry done with dropping mercury electrode is known as polarography.  A graph which represents current Vs voltage is called polarogram.

(c)

Interpretation Introduction

Interpretation:

The change in reduction potential when platinum electrode is used monitor has to be explained.

Concept introduction:

In the electrochemical reactions the relation between current and voltage is noted and this technique is called voltammetry.  A graph which represents current Vs voltage is called voltammogram.

Macmillan Learnin When an unknown amine reacts with an unknown acid chloride, an amide with a molecular mass of 163 g/mol (M* = 163 m/z) is formed. In the infrared spectrum, important absorptions appear at 1661, 750 and 690 cm-1. The 13C NMR and DEPT spectra are provided.
