What Does the "p" in pH Stand For?
The "p" in pH stands for "power." This designation is derived from the German word "Potenz," which translates to "power" or "potential."
Understanding pH Scale
The pH scale is a logarithmic scale used to measure the acidity or basicity of a solution. It ranges from 0 to 14, where:
- A pH of 7 is considered neutral (pure water).
- A pH less than 7 indicates acidity (higher hydrogen ion concentration).
- A pH greater than 7 indicates basicity (lower hydrogen ion concentration).
Measurement of Hydrogen Ion Concentration
The pH scale specifically measures the concentration of hydrogen ions (H+) in a solution. This is crucial because:
- Acidic Solutions: Higher concentrations of H+ ions lead to lower pH values. For example, lemon juice has a pH of around 2, indicating high acidity.
- Basic Solutions: Lower concentrations of H+ ions correspond to higher pH values. For instance, bleach has a pH of around 12, indicating it is basic.
Importance of pH
Understanding pH is essential in various fields, including:
- Chemistry: It helps in determining the nature of chemical reactions.
- Biology: Enzyme activity and metabolic processes are pH-dependent.
- Environmental Science: pH affects aquatic life and soil health.
In summary, the correct answer is option 'B' because the pH scale effectively measures the hydrogen ion concentration in a solution, which determines its acidity or basicity.
