Chapter 9, Problem 88P

Interpretation Introduction

Interpretation:

Themolarity of $\text{HCl}$ needs to be determined, if 5.00 mL of it is neutralizes by 17.2 mL of 0.15 M $\text{NaOH}$ solution.

Concept Introduction:

An acid is a substance that gives ${\text{H}}^{\text{+}}$ ions in its solution whereas a basic substance gives ${\text{OH}}^{\text{-}}$ ions in its solution. The reaction of an acid HA with a base BOH can be written as:

  $\text{HA + BOH}\text{}\underset{}{\to }{\text{ BA + H}}_{\text{2}}\text{O}$

Here BA stands for salt and the reaction named as neutralization reaction. Thus the reaction of an acid with a base results in the formation of salt and water. The salt is an ionic compound that is formed by the combination of the cation ( ${\text{B}}^{\text{+}}$ ) from base and anion ( ${\text{A}}^{\text{-}}$ ) from acid and forms salt BA.
