Chapter 14, Problem 14.74SP

(a)

Interpretation Introduction

Interpretation:

Given acids are to be arranged in increasing acid strength.

Concept Introduction:

Strong acids:

In strong acids, the ionization of acid is complete.  This implies that the concentration of the hydrogen ion or hydronium ion will be equal to the initial concentration of the acid at equilibrium.

(b)

Interpretation Introduction

Interpretation:

Given acids are to be arranged in order of decreasing percent dissociation and also concentration of ${\text{H}}_{\text{3}}{\text{O}}^{\text{+}}$ in a solution of each acid should be estimated.

Concept Introduction:

Percent dissociation:

It is defined as concentration of dissociated acid divided by the concentration of the acid times $100\%$.

$\text{Percent}\text{dissociation =}\frac{{\left[\text{HF}\right]}_{\text{dissociated}}}{{\left[\text{HA}\right]}_{\text{initial}}}\times 100\%$
