Properties of ammonia gas
Thread Content
According to the information I found, the solubility of ammonia in water is 35% (at 20 degrees Celsius). In other words, the maximum concentration of ammonia in water is 35%. I’m not sure if this is correct; please let me know your thoughts. Points will be given for helpful responses
Here, the issues of volume concentration and mass concentration need to be considered.
Ammonia is highly soluble in water, with a solubility ratio of 1:700. The density of ammonia under standard conditions is 0.7081 g/L. The density of 100 g of water is 100 mL, or 0.1 L; therefore, 0.1 L of water can dissolve 70 L of ammonia. The weight of 70 L of ammonia is 0.7081 × 70 = 49.567 g. Thus, the solubility of ammonia in water is 49.567 g per 100 g of water
This data is at atmospheric pressure; under pressure, 99.9% ammonia solution (commonly known as liquid ammonia) is also available
Ammonia is highly soluble in water; at 25°C and 101 kPa, ammonia gas and water are in a volume ratio of 700:1, and its solubility decreases as the temperature rises； Refer to the table below for specific values
