Chapter 14.9, Problem 81PP

Interpretation Introduction

Interpretation: The concentration of H₃O+ should be completed.

Concept Introduction :

• pH stands for "potential of hydrogen", it is a measure of alkalinity or acidity of water-soluble substances. pH number ranges from 0 to 14.
• pH is a logarithmic scale which specify the acidity or basicity of the solution.

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

pOH = -log [OH]^-

pH + pOH = 14

• Neutral solution- A solution is neutral if $pH=7$
• Acidic solution- A solution is acidic if $pH<7$
• Basic solution- A solution is basic if $pH>7$
