Chapter 15, Problem 79E

(a)

Interpretation Introduction

To determine: The pH of the resulting solution on mixing 0.115M (molar) $\text{HBr}$(hydrogen bromide) with 0.125 M of ${\text{HCHO}}_{\text{2}}$ (formic acid).

(b)

Interpretation Introduction

To determine: The pH of the resulting solution on mixing 0.150M ${\text{HNO}}_{\text{2}}$(nitrous acid) with 0.085 M of ${\text{HNO}}_3$ (nitric acid).

(c)

Interpretation Introduction

To determine: The pH of the resulting solution on mixing 0.185M ${\text{HCHO}}_{\text{2}}$(formic acid) with 0.225 M of ${\text{HC}}_{\text{2}}{\text{H}}_3{\text{O}}_2$ (acetic acid).

(d)

Interpretation Introduction

To determine: The pH of the resulting solution on mixing 0.050 M ${\text{HC}}_{\text{2}}{\text{H}}_3{\text{O}}_2$(acetic acid) with 0.050 M of $\text{HCN}$ (hydrocyanic acid).
