Chapter 9, Problem 9.13QAP

Interpretation Introduction

(a)

Interpretation:

The reason for decrease in atomic absorption signal for iron in presence of large concentration of sulphate ion in hydrogen-oxygen flame needs to be explained.

Concept introduction:

In a defined space, the amount of a substance gives its concentration. A substance’s capacity to absorb specific wavelength light gives its absorbance.

Interpretation Introduction

(b)

Interpretation:

The ways of overcoming interference of sulphate in iron determination needs to be explained.

Concept introduction:

In a defined space, the amount of a substance gives its concentration. A substance’s capacity to absorb specific wavelength light gives its absorbance.
