Study Notes
pH Meter Principles
- A pH meter measures the pH of a solution, which is the negative logarithm of the hydrogen ion concentration.
- The difference in electrical potential is measured by a pH meter through a voltaic cell, where the electrode potential difference between a reference electrode and a pH-sensitive electrode is proportional to the pH.
pH Meter Applications
- pH meters are used in various applications, including laboratory analyses, industrial processes, and environmental monitoring.
- Knowledge of pH is useful in chemical laboratory analyses because it helps to identify the nature of a substance, monitor chemical reactions, and detect the presence of contaminants.
- In agriculture, one of the uses of pH meters is to determine the soil pH, which is essential for optimal plant growth, as it affects the availability of nutrients and the microbial activity in the soil.
