Chapter 7.2, Problem B7.1P

(a)

Interpretation Introduction

Interpretation:

Absorbance versus concentration of complex in the solution plot is to be drawn. Also, the slope and $\text{y-intercept}$ of the line is to be calculated.

Concept introduction:

Absorbance can be described as the measure of the amount of light absorbed by the sample. As the concentration increases, the absorbance increases. As the dilution increases, the concentration decreases.

The expression to calculate the slope of the line from two points is as follows:

  $m=\frac{y_2-y_1}{x_2-x_1}$        (1)

Here, $x,y,x\text{and }y$ are the coordinates of the point.

(b)

Interpretation Introduction

Interpretation:

The concentration diluted solution is to be calculated. Also, the initial concentration of the original solution is to be calculated.

Concept introduction:

Absorbance can be described as the measure of the amount of light absorbed by the sample.

As the concentration increases, the absorbance increases. As the dilution increases, the concentration decreases.
