Chapter 16, Problem 13E

Interpretation Introduction

Interpretation:

The pH of the given solutions is to be calculated by Henderson-Hasselbalch equation.

Concept introduction: The molecular formula provides the total number of atoms and kinds of atom in a molecule.

Molecular formula of a particular molecule is the chemical formula that provides the total number of atoms of every element in each molecule of a substance.

To determine: The pH of the solutions, $0.125\text{M}$ in $\text{HClO}$ and $0.150\text{M}$ in $\text{KClO}$ , $0.175\text{M}$ in ${\text{C}}_2{\text{H}}_5{\text{NH}}_2$ and $0.150\text{M}$ in ${\text{C}}_2{\text{H}}_5{\text{NH}}_3\text{Br}$ , $10.0\text{g}$ of ${\text{HC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ and $10.0\text{g}$ of ${\text{NaC}}_{\text{2}}{\text{H}}_{\text{3}}{\text{O}}_{\text{2}}$ in $150\text{ml}$ of solution by Henderson-Hasselbalch equation.
