Verified step by step guidance1
Understand that pH is a measure related to the acidity or basicity of an aqueous solution.
Recall the definition of pH, which is based on the concentration of hydrogen ions (H\textsuperscript{+}) in the solution.
Express pH mathematically as \(pH = -\log\left([H^{+}]\right)\), where \([H^{+}]\) is the molar concentration of hydrogen ions.
Recognize that pH does not measure temperature, hydroxide ion concentration directly, or ionic strength, but specifically the hydrogen ion concentration.
Conclude that the pH scale quantifies how acidic or basic a solution is by indicating the hydrogen ion concentration on a logarithmic scale.
