Chapter 17, Problem 28QP

Interpretation Introduction

Interpretation:

The molar mass of the acid that $25.0\text{ mL}$

of the solution required potassium hydroxide for neutralization, is to be determined.

Concept introduction:

Diprotic acid means an acid with two hydrogen atoms in its molecule, capable of being released or ionizing in water.

The neutralization reaction is a reaction in which an acid and base react to form water and a salt, involving the combination of ${\text{H}}^{\text{+}}{\text{and OH}}^{\text{-}}$ ions to generate water.

The number of moles of ${\text{H}}_{\text{2}}\text{A}$ reacted from the volume and molarity as:

$\text{number}\text{of}\text{moles}\text{=}\text{Volume×}\text{molarity×}\frac{\text{1}\text{mol}{\text{H}}_{\text{2}}\text{A}}{\text{2}\text{mol}\text{KOH}}$
