Chapter 17, Problem 101QRT

(a)

Interpretation Introduction

Interpretation:

The molarity of ${\text{Ag}}^{+}$ in the solution which is required $16.7\text{mL}$ of $0.015\text{M}$ potassium iodide solution to titrate $25.0\text{mL}$ of the silver solution has to be calculated.

Concept Introduction:

Titration is an analytical method which is used to determine the strength of the unknown solution.  The standard solution used in titration present in the buret.  The volume of the standard solution consumed in the reaction is measured by volume scale on the buret.

(b)

Interpretation Introduction

Interpretation:

The value of $K_{\text{sp}}$ for silver iodide has to be calculated.

Concept Introduction:

The cell potential of the cell is defined as a potential difference between two electrodes.  Inside a cell, redox reaction takes place which consists of reduction half-reaction and oxidation half-reaction.  The Nernst equation is used to calculate the cell potential.
