Chapter 16, Problem 149E

Interpretation Introduction

Interpretation:

The concentration of hydroxide ion in a $20.00\text{-mL}$ sample of an unknown is to be calculated when $14.75\text{mL}$ of $0.248\text{M}$ sulfuric acid is used in a neutralization reaction.

Concept introduction:

The molarity of a solution is defined as the number of mole of solute dissolved in one liter of the solution. The formula for molarity is given by the expression as shown below.

$\text{M}=\frac{\text{n}}{\text{V}}$

Neutralization is the process in which an acid and base react with each other to give salt and water. The general reaction of acid and base is shown below.

$\text{AH}+\text{BOH}\to \text{AB}+{\text{H}}_{\text{2}}\text{O}$
