When ammonium chloride dissolves in water, the solution becomes colder. (b) Why does the solution form?

Video transcript

Hello everyone. Today, we have the following problem. The temperature of the system decreases when potassium chlorate is dissolved in water. Which of the following statements explains why the solution is formed. So when potassium chloride dissolves Mrs, potassium chlorine as a solid, it is going to dissolve, dissolve to form potassium ions and chlorate ions. And so when this occurs, the number of particles in the solution are going to increase the number of particles increase. And this process is going to lead to an increase in the disorder or chaos of the system. This is going to result in an increase in the entropy of the system, which is, which is defined as the measure of disorder in a system. And so we can say that when we increase the entropy, this increase is going to drive the solution formation. And so the answer choice d best applies to that the increase in entropy makes up for the increase in entropy of the system. And this drives the solution formation. And with that, we've answered the question overall, I hope this helped. And until next time
