Interpretation Introduction

Interpretation:

A tactful memorandum to my boss to save him additional public embarrassment has to be drafted.

Concept Introduction:

$pH$ Scale: 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)

When both the cation and the anion react with water, the pH of the solution will depend on the relative magnitudes of ${\text{K}}_{\text{a}}$ for the cation and ${\text{K}}_{\text{b}}$ for the anion.
