Type: Property
Description: pH is a scale used to specify the acidity or basicity of an aqueous solution. It is logarithmic and inversely indicates the concentration of hydrogen ions (H+) in the solution. The pH scale ranges from 0 to 14, with 7 being neutral, values less than 7 indicating acidity, and values greater than 7 indicating alkalinity.
Attributes:
- Unit of Measurement: pH (unitless)
- Factors Influencing pH:
- Chemical Composition: The presence of acidic or basic substances.
- Temperature: pH can change with temperature fluctuations.
- Concentration: Dilution of acids and bases affects pH levels.
- Range:
- Acidic: 0-6.9 (e.g., lemon juice, vinegar)
- Neutral: 7 (e.g., pure water)
- Basic: 7.1-14 (e.g., baking soda, ammonia solution)
Relationships:
- Related Properties:
- Electrical Conductivity: Often correlates with pH in terms of the ion concentration.
- Buffer Capacity: The ability of a solution to resist changes in pH when an acid or base is added.
- Applications:
- Agriculture: Monitoring soil pH to ensure optimal plant growth.
- Aquaculture: Maintaining proper pH levels for aquatic life.
- Water Treatment: Adjusting pH to meet safe drinking water standards.
