The water solubility was measured to be 482,000 mg/L at 25 °C.
Description of key information
Anhydrous ammonia is very soluble in water: reported water solubility values are 482000 -531000 mg/L.
Key value for chemical safety assessment
- Water solubility:
- 482 000 mg/L
- at the temperature of:
- 25 °C
Additional information
The water solubility of anhydrous ammonia was measured to be 482 g/L at 25 °C (Lange's Handbook) and 510-531 g/L (Merck Index). The Handbook of Environmental Data on Chemicals gives solubility values of 531,000 mg/L at 20°C and 444,000 mg/L at 28°C. The water solubility decreases with increasing temperature, from 34 vol% at 20°C to 18 vol% at 30°C (Merck Index).
The substance is very soluble in water.
