# (a) Interpretation: The equation for V s needs to be derived using the Faraday’s law. Concept introduction: The equation for V s is represented as follows: V s = Q n F C Here, Q = Charge n = Number of moles of electrons. F = Faraday’s constant C = Molar concentration of the metal ion. ### Principles of Instrumental Analysis

#### Solutions

Chapter 25, Problem 25.17QAP
Interpretation Introduction

## (a)Interpretation:The equation for Vs needs to be derived using the Faraday’s law.Concept introduction:The equation for Vs is represented as follows:Vs=QnFCHere,Q= Chargen= Number of moles of electrons.F= Faraday’s constantC= Molar concentration of the metal ion.

Interpretation Introduction

### (b)Interpretation:The total charge needed to strip the silver from the electrode needs to be determined. Also, the volume of the solution used to deposit the silver needs to be determined,Concept introduction:The equation for Vs is represented as follows:Vs=QnFCHere,Q= Chargen= Number of moles of electrons.F= Faraday’s constantC= Molar concentration of the metal ion.

Interpretation Introduction

### (c)Interpretation:The experiments need to be suggested to show whether all the Ag+ was reduced to Ag(s) in the step of deposition or not.Concept introduction:Linear scale voltammetry is used to compare the data for the metal reduction in the deposition step.

Interpretation Introduction

### (d)Interpretation:Whether it matters when the shape of the drop is hemisphere or not needs to be explained.Concept introduction:Visual measurement of droplet which is spherical or hemispherical in shape.
