![pH expresses the molar concentration of hydronium ions in an
aqueous solution on a logarithmic scale. (Note that it is
common to use the hydrogen ion, H*, to represent the
hydronium ion, H3O+.)
pH = -log[H3O+]
[H3O+] = 10-PH
As pH decreases, acidity increases. As pH increases, acidity
decreases.
• Acidic solution: pH < 7
• Neutral solution: pH = 7
• Basic solution: pH > 7
