Chapter 16, Problem 16.73QP

Interpretation Introduction

Interpretation:

The pH of a $\text{0}\text{.36}\text{M}{\text{CH}}_{\text{3}}\text{COONa}$ solution has to be calculated

Concept Information:

The acidity or basicity of an aqueous solution was called using a numerical scale called pH scale.

Based on pH of the solution, salt solutions can be classified as

• Acidic        -    (pH will be less than seven)
• Basic         -    (pH will be more than seven)
• Neutral     -    (pH will be equal to seven)

For calculation of pH, the following formula is used,

$\text{pH}\text{=}-\log {\text{[H}}^{\text{+}}\text{]}$

For calculation of pOH, the following formula is used,

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

From definition of pH and pOH, we get at room temperature,

$\text{pH}\text{+}\text{pOH}\text{=}\text{14}$

To Calculate: The pH of a $\text{0}\text{.36}\text{M}{\text{CH}}_{\text{3}}\text{COONa}$ solution
