An Experiment to Determine the Efficiency of Isopropanol as a Solution
An experiment was carried out to determine whether isopropanol (IPA) solution in water is a real or ideal solution. If the plot of solution volume of IPA and water versus the mole fraction of IPA in the solution (XIPA) was linear, then the solution would be classified as ideal. If the plot was not linear, IPA solution would...

A Study on Copper as an Antimicrobial Solution
The antimicrobial properties of copper are documented in ancient
Egyptian medical texts written before 2200 B.C. Copper has been used for
hygienic and medical applications for thousands of years. Much of the
research going into antimicrobial surfaces has focused on inorganic
surfaces such as copper and silver. One of the ne...
