Ammonia Solubility in Water and Temperature
On the relationship between the solubility of ammonia in water and temperature
Ammonia is a common chemical substance, and the relationship between its solubility in water and temperature is quite important to chemists.
Looking at the state of normal temperature, the amount of ammonia dissolved in water is still considerable. Because of the force of hydrogen bonds between ammonia molecules and water molecules, this force promotes ammonia to dissolve in water. However, the temperature changes, the solubility of ammonia varies accordingly.
If the temperature gradually rises, the solubility of ammonia in water gradually decreases. This is not difficult to understand. When the temperature is high, the thermal movement of molecules intensifies, and the power of ammonia molecules to escape from the water surface increases. Ammonia that was originally soluble in water breaks free from the shackles of water molecules and escapes from the gas phase.
In the past, there were experiments in which water and ammonia were held in a closed container and gradually heated up. At first, the amount of ammonia dissolved in water was quite sufficient, and the aqueous solution was alkaline, which could make phenolphthalein turn red. And when the temperature increases, ammonia escapes more and more, the alkalinity of the aqueous solution gradually weakens, and the color of phenolphthalein is also light. This experiment shows an inverse relationship between temperature and ammonia solubility.
As for industrial applications, in the treatment of ammonia after synthesis, if you want to obtain high-purity ammonia, you can use the method of heating to make ammonia escape from the ammonia aqueous solution. In the refrigeration industry, liquid ammonia gasification refrigeration also uses the characteristics of ammonia solubility at different temperatures.
Overall, the solubility of ammonia in water is closely related to temperature, and the solubility decreases when the temperature increases. This law is of great significance to scientific research and industry, and it can benefit many production and research issues.
