There are multiple similarities between the distilled water and the filtrate. For example their boiling points were very close, never ranging more than 10 degrees apart from one another. Another similarity was the acid/base test. The results were not identical, but their color was extremely similar. Also density was somewhat close only having a difference of 0.23 g/mL. No test had perfectly alike results, but there was no dramatic differences with in these three tests that we conducted.
