- <u><em>2)NH</em></u><em><u>₃</u></em>
Explanation:
The answer choices of this question are:
<h2 /><h2>Solution</h2>
The key to answer this question is to realize that <em>NH₃</em> is a gas at the given temperatures.
The solutilibty of all gases always decreases when the temperature increases. Thus, the solubility of NH₃ will decrease when the temperature rises from 10ºC to 50ºC.
The reason for this behavior of gases is that the temperature and the kinetic energy of the particles are directly proportional. Thus, as the temperature incrases the kinetic energy of the particles increases.
As the kinetic energy of the molecules of gas in the liquid solution increases, their speeds also increase, meaning that more molecules will escape from the solution to the gas phase, leaving the soluton with less dissolved gas molecules.
