Chapter 14, Problem 114E

Interpretation Introduction

Interpretation: The number of ${\text{H}}^{\text{+}}$ ions and ${\text{OH}}^{-}$ ions of given concentration of $\text{HCl}$ are to be calculated.

Concept Introduction: Molarity of a substance is defined as the number of moles of solute present in one liter of solution. It is represented by the symbol “$\text{M}$”.

The relation between moles and molarity is expressed as:

$\text{Molarity}=\frac{\text{Moles solute}}{\text{Litre solution}}$

The relation between milliliter and liter is represented as:

$\text{1}\text{mL}={\text{10}}^{-3}\text{ L}$

The ion product constant for water is the product of concentration of ${\text{H}}_3{\text{O}}^{+}$ and ${\text{OH}}^{-}$ ions in aqueous solution.

The expression of ion product constant for water is written as:

$K_W=\left[{\text{H}}_3{\text{O}}^{+}\right]\left[{\text{OH}}^{-}\right]$
