Chapter 16.4, Problem 5PPC

(a)

Interpretation Introduction

Interpretation:

The two whole numbers between which the pOH of the given solutions will be for the given hydroxide ion concentrations has to be determined

Concept Information:

pOH definition:

The $\text{pOH}$ of a solution is defined as the negative base-10 logarithm of the hydroxide ion ${\text{[OH}}^{\text{-}}\text{]}$ concentration. $\text{pOH}$ scale is analogous to pH scale.

$\text{pOH}\text{=}{\text{-log[OH}}^{\text{-}}\text{]}$

Determining pOH without calculation:

The pOH scale is the reverse of the pH scale.

On the pOH scale, numbers below 7 indicate a basic solution, whereas numbers above 7 indicate an acidic solution.

The pOH benchmarks work the same way the pH benchmarks do.

For example:

A hydroxide ion concentration between $1\times {10}^{-4}M$ and $1\times {10}^{-5}M$ corresponds to a pOH between 4 and 5.

To Determine: The two whole numbers between which the pOH of the given solutions will be for the given hydroxide ion concentrations
