Match the diagrams (1 or 2) with the following: (9.1)

b. a nonpolar solute and a polar solvent

Accepted Answer

Welcome back, everyone. We need to match the given figure with the appropriate description where green correlates to solute and blue correlates to solvent. Looking at our answer choices, choice A states that we have a nonpolar solute and polar solvent. Choice B states that we have a polar solute and nonpolar solvent. Choice C states that both the solute and solvent are both polar choice D states that the solute and solvent are both nonpolar and choice E states that choices A and B are both true and correct. So observing our given diagram, we can observe that we have green tightly packed particles which according to our key represents solute recall that solute is our substance being dissolved because this solute is densely packed. We're going to understand that it's therefore likely in the solid phase. Next, beneath our densely packed green colored particles, we have a second substance which fills the remaining area of our diagram or container N is colored blue. And based on our key, this would correlate to solvent, our substance that is dissolving the other substance potentially. Now, in this case, this solvent does not appear as particles. And so we have just the color blue, filling up the area of our container. So because this fills the remaining area of the container, this substance is likely in the liquid phase. Now, ultimately, we can summarize that we have two distinguishable substances or so therefore, our substances do not mix. So we ultimately have two different types of substances. And with the principle of like dissolves, like as far as a fully mixed solution, where we would not be able to identify two different types of phases, we would just have one homogenous phase. We would therefore interpret that these two substances in our diagram have different polarities in other properties. And thus, we cannot specifically identify which would be polar or nonpolar. However, that is only because we do not know the identity of our given substances in the diagram. Now we can't just assume that the blue area is water as the substance in the liquid phase due to the fact that again, we are not given the identity and it could happen to be a nonpolar solvent in which water is not nonpolar. Water recall is polar. So looking at our answer choices, we're going to rule out the answer choices C as well as D which state that both substances would have the same properties, either being polar, both polar or both nonpolar. And then that leaves us with being able to also rule out choices A and B due to the fact that we do not know which of our substances is either polar or nonpolar. So we can't say that either A is only true or either B is only true. We can only consider both A and B which leaves us with choice E as the best and most correct answer. And actually, we also had a choice of which considered choices C and D, which again, we already ruled out choices C and D. So again, that leaves us with choice E which states that choices A and B are both correct. So E is our final answer. Our two substances can either be nonpolar, solute and polar solvent or polar solute and nonpolar solvent. I hope that this made sense and let us know if you have any questions.
