What does the term "pH" measure in substances?

  1. Plant Growth Regulator (PGR)

  2. Physical Incompatibility

  3. Point of Runoff

  4. Acidity and alkalinity

The correct answer is: Acidity and alkalinity

The term "pH" measures the acidity or alkalinity of a substance. pH stands for "potential of Hydrogen" and refers to the concentration of hydrogen ions in a solution. A pH value below 7 indicates acidity, while a pH value above 7 indicates alkalinity. Understanding the pH of a substance is crucial in pesticide application as it can affect the efficacy and stability of the pesticide being used. Options A, B, and C are not correct as they do not relate to the measurement of acidity and alkalinity, which is the main purpose of the pH scale.
