Question
Chapter 25, Problem 25.7QAP
Interpretation Introduction
Interpretation:
The purpose of electrodeposition step in stripping analysis is to be stated.
Concept introduction:
The analyte those have been deposited may be reduced or oxidized and hence responsible for the production of the large current. Then the electro deposition step in stripping analysis is used to concentrate these analyte on electrode’s surface.
