Ozone is highly soluble in water, with a solubility of 109 mg/l at 25°C. This is significantly higher than oxygen, which has a solubility of only 8 mg/l under the same conditions.
Ozone Solubility Compared to Oxygen
To highlight this difference, consider the following table:
| Gas | Solubility at 25°C (mg/l) |
|---|---|
| Ozone | 109 |
| Oxygen | 8 |
This comparison clearly demonstrates ozone’s exceptional solubility in water.
Practical Implications of Ozone Solubility
The high solubility of ozone in water has several important applications:
- Water Treatment: Ozone is used in water treatment plants as a powerful disinfectant and oxidant. It effectively eliminates pathogens and degrades organic pollutants.
- Industrial Processes: Ozone is used in various industrial processes for applications like bleaching, oxidation, and disinfection.
- Scientific Research: The solubility of ozone in water is often a crucial factor in scientific studies concerning its behavior and impact.
Factors Affecting Ozone Solubility
While 109 mg/l is a benchmark at 25°C, it is important to note that other factors can influence ozone solubility:
- Temperature: Solubility generally decreases as temperature increases.
- Pressure: Higher pressure typically increases the solubility of gases in liquids.
- Presence of other substances: Dissolved salts and organic matter in water can affect ozone solubility.
Ozone's high water solubility plays a key role in its diverse applications. Understanding its behavior in water is essential for maximizing its benefits in various fields.
