Chapter 16.4, Problem 6PPC

Interpretation Introduction

Interpretation:

The value of the exponent in the hydronium ion concentration for the given solutions has

be given

Concept Information:

pOHdefinition:

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.

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

On rearranging, the concentration of hydroxide ion ${\text{[OH}}^{\text{-}}\text{]}$ can be calculated using pOH as follows,

${\text{[OH}}^{\text{-}}\text{]}\text{=}{\text{10}}^{\text{-pOH}}$

To Give: The value of the exponent in the hydronium ion concentration for the given solution with pOH 2.90
